LM2904DG4

LM2904DG4 - Dual 26V 700kHz Op Amp | Texas Instruments

Texas Instruments LM2904DG4 is a dual general-purpose operational amplifier with two independent amplifiers, a 26 V maximum supply rating, a 700 kHz gain-bandwidth product, and an 8-pin SOIC package. Each amplifier supports single-supply operation up to 26 V or dual-supply operation up to ±13 V, while the 0.7 mA typical supply-current drain remains independent of supply voltage. An operational amplifier is an analog signal-processing IC that amplifies the voltage difference between its non-inverting and inverting inputs. The LM2904 belongs to the operational-amplifier hierarchy, combining high open-loop voltage gain with negative feedback to set closed-loop behavior. Its two independent channels make it useful wherever two separate analog signals must be conditioned within the same package. Key characteristics include a 700 kHz gain-bandwidth product, a 0.3 V/µs slew rate, and a 0.7 mA typical supply-current drain. The common-mode input range includes ground, allowing single-supply systems to accept input signals near the lower supply rail. These characteristics support cost-sensitive general-purpose designs rather than precision or high-speed instrumentation. Internally, the LM2904 uses a conventional bipolar operational-amplifier architecture, with two independent amplifier channels and an eight-pin SOIC package. The 700 kHz gain-bandwidth product permits useful closed-loop bandwidth at moderate gain, while the 0.3 V/µs slew rate defines how quickly the output can move under large-signal conditions. Its low, supply-independent current draw helps maintain system efficiency. Typical uses include signal conditioning in industrial control systems, feedback and drive networks in power-conversion products, audio preamplifier stages, sensor interfaces, and general dual-amplifier modules. The tube packaging identified for LM2904DG4 is particularly appropriate for production assembly processes that use tube-fed through-hole or tube-to-tape conversion equipment. When designing around the LM2904DG4, verify input and output common-mode limits at the selected supply voltage, provide adequate bypassing close to the supply pins, and confirm that the required signal bandwidth and output swing remain within the amplifier's operating limits. Stable operation also depends on appropriate feedback compensation for the selected gain and load. This product page combines manufacturer specifications, package and pin information, engineering application guidance, and a structured comparison with compatible LM2904-family devices. It is designed to accelerate component selection and PCB planning while keeping the key trade-offs explicit.

LM2904DMR2G - Dual 3-26V Low-Power Op Amp | onsemi
LM2904DMR2G

LM2904DMR2G - Dual 3-26V Low-Power Op Amp | onsemi

onsemi LM2904DMR2G is a dual, general-purpose operational amplifier with a 3 V to 26 V supply range, two amplifier circuits, and an 8-MSOP surface-mount package. The LM2904 family provides low power drain, supports single-supply or split-supply operation, and permits common-mode input voltages to extend toward ground or VEE. These characteristics make the device useful in industrial signal-conditioning, control, and sensor-interface circuits. An operational amplifier is a voltage-gain building block used throughout analog electronics. Its differential input stage compares two input voltages and drives an output to amplify the difference between them. The LM2904 belongs to the bipolar operational-amplifier hierarchy, combining two amplifier channels in one package for general-purpose precision, control, and instrumentation applications. The LM2904DMR2G provides two amplifier circuits, a gain-bandwidth product of 1 MHz, and a maximum supply voltage of 32 V. Its specified operating temperature range is -40°C to 105°C. The 3 V to 26 V operating supply range supports low-voltage systems as well as higher-voltage industrial circuits when the total supply and input limits are observed. The bipolar internal design favors low-cost, general-purpose signal conditioning rather than rail-to-rail input or output operation. Its common-mode input range extending to ground or VEE is particularly useful with single-supply sensors whose signals remain near the lower rail. Single-supply and split-supply operation gives designers flexibility when building signal paths around positive-only or bipolar reference voltages. Typical uses include low-side current monitoring, pressure and temperature sensor interfaces, audio preamplifier stages, industrial control loops, and general amplifier or buffer configurations. The two independent channels can process different signals or implement a more complete analog function within one compact 8-MSOP package. Designers should check input and output common-mode limits at the selected supply voltage and load current. Stable operation with capacitive loads may require an isolation resistor or an application-specific compensation network. PCB placement should keep input and feedback traces short, provide a stable ground reference, and avoid routing sensitive signals beside switching nodes or high-current power paths. This page combines the LM2904DMR2G package and operating characteristics with practical design guidance, verified drop-in candidates, application analysis, and a parameter-by-parameter comparison. It is intended to help engineers confirm compatibility, assess supply and thermal margins, and select an amplifier that can be implemented without unnecessary PCB redesign.

LM2904DR2

LM2904DR2 - Dual 3-26V Operational Amplifier | onsemi

The onsemi LM2904DR2 is a dual general-purpose operational amplifier designed for low-power signal-conditioning applications from a single supply or split supplies. It operates across a 3 V to 26 V total supply range, accepts inputs that extend toward ground or VEE, and is packaged in an 8-pin SOIC for standard surface-mount assembly. The device contains two amplifiers in one package while retaining the familiar LM358-family architecture. An operational amplifier is a high-gain analog building block used to amplify voltage differences, buffer signals, compare voltages, and drive feedback-controlled circuits. The dual operational amplifier category belongs to the broader hierarchy of operational amplifier, linear amplifier, analog IC, and semiconductor. This makes the LM2904DR2 suitable for both general-purpose precision-adjacent signal conditioning and conventional industrial control circuits where a low-power, dual amplifier simplifies board layout. The LM2904DR2 combines two amplifier channels in one 8-pin SOIC. Its single-supply operating range is listed as 3 V to 26 V, while the associated dual-supply capability supports operation from approximately plus or minus 16 V, corresponding to a 32 V total supply. The common-mode input range extends to ground in single-supply configurations and to VEE in split-supply configurations. These characteristics make each channel suitable for noninverting and inverting amplifier, voltage follower, comparator, and general feedback-control arrangements. The low-power operating characteristics allow the device to be used in battery-powered instrumentation, industrial sensing, sensor interfaces, and control systems where dual-channel analog processing is required without a high-power amplifier family. Its differential inputs support feedback arrangements in which one input receives the source signal and the other receives the feedback or reference network. The two independent channels can also process different signals within the same package. Typical applications include low-level sensor conditioning, current-loop receivers, audio preamplifier stages, active filtering, comparator circuits, and industrial control interfaces. In a current-loop receiver, for example, the amplifier can amplify a small voltage across a sense resistor while the common-mode range supports signals referenced toward the lower supply rail. In a dual-channel design, one channel can condition a measurement while the other performs monitoring or buffering. Layout should prioritize short feedback paths, stable input grounding, and careful decoupling of the supply pins. Place the device close to the analog signal source when trace lengths permit, route high-impedance input nodes away from switching nodes, and use the manufacturer datasheet pin description table when assigning PCB tracks. Decoupling requirements, exact electrical limits, and compensation guidance should be taken directly from the applicable onsemi datasheet. This page combines the exact LM2904DR2 ordering information with package, supply-voltage, application, and replacement guidance. It also distinguishes pin-compatible alternatives from merely similar amplifier functions, helping engineers evaluate PCB reuse, supply compatibility, and sourcing without changing the original 8-pin SOIC footprint.

LM2904DR2G

LM2904DR2G - Dual 3-32V Op Amp, 8-SOIC | onsemi

onsemi LM2904DR2G is a dual general-purpose operational amplifier with two independent amplifier channels, a 3 V to 32 V supply-voltage range, and an 8-SOIC surface-mount package. The device supports single-supply or split-supply operation, and its common-mode input range extends to ground or VEE, making it suitable for systems using low positive supply voltages. An operational amplifier is an analog signal-processing IC that amplifies the voltage difference between its inverting and non-inverting inputs. The LM2904 belongs to the dual operational amplifier family within the broader operational amplifier, analog IC, and semiconductor hierarchies. Its two channels can amplify two signals independently, or one channel can be used as a buffer while the other performs amplification, filtering, or comparison. The principal advantages include low power drain, common-mode input operation extending to ground or VEE, and flexible single- or dual-supply configurations. The 3 V minimum supply supports modern low-voltage systems, while the 32 V maximum accommodates higher industrial rails. The -40°C to +105°C operating-temperature range supports applications across consumer, instrumentation, industrial-control, and power-management equipment. The LM2904 uses a bipolar operational-amplifier architecture. Each channel includes differential inputs and an output stage designed for general-purpose signal conditioning. Unlike rail-to-rail-input devices, its useful input range depends on the selected supply arrangement and common-mode limits. Designers should therefore verify signal levels against the operating conditions in the manufacturer datasheet rather than assuming full rail-to-rail input capability. Typical applications include low-side current monitoring, sensor-signal conditioning, active filtering, buffer stages, audio preamplification, threshold detection, and general industrial control. It is especially useful when a design requires operation from a single positive supply while processing signals that approach the negative supply rail, which is represented by ground in a single-supply circuit. For reliable implementation, place the input, feedback, and decoupling components close to their associated pins, use a stable low-noise power source, and check output-current and common-mode limits over the complete temperature range. Bypass capacitors should connect directly to the supply pins to minimize parasitic inductance and preserve stability. This product page combines the operating characteristics, pin assignments, application guidance, drop-in comparison, and practical layout considerations needed to evaluate the LM2904DR2G for a new analog signal chain.

LM2904DR2GH

LM2904DR2GH - Dual 1MHz Op Amp, 3-32V Supply, SOIC-8 | onsemi

The onsemi LM2904DR2GH is a dual general-purpose operational amplifier with two independent amplifier channels in an 8-pin SOIC (D) package. It offers a gain-bandwidth product of 1 MHz, single-supply operation from 3.0 V to 32 V, and a common-mode input range that extends to the negative supply rail, making it a drop-in choice for legacy and new analog signal-chain designs. An operational amplifier is a high-gain differential amplifier whose inverting and non-inverting inputs are compared, producing an output that drives the difference between them. The dual-amplifier form factor halves board area for common tasks such as buffer and gain stages, level shifting, active filters, transducers, and sensor conditioning. In the power-management hierarchy, op amps sit alongside regulators and references as fundamental analog building blocks, and the LM2904 family is one of the most widely cloned dual general-purpose amplifier families in the industry. Key features of the LM2904DR2GH include short-circuit-protected outputs, a true differential input stage, internally compensated operation (no external compensation network required), low input bias currents, and ESD clamps on the inputs that improve ruggedness without degrading signal integrity. Because the amplifier is internally compensated, it is stable with unity-gain noise gain, which simplifies feedback design in buffer and general-purpose configurations. The common-mode input range extending to the negative supply is the defining architectural advantage in single-supply systems. The input stage can operate with signals referenced near 0 V while the device runs from a single positive rail, removing the need for a negative bias supply or an artificial ground in sensor, audio, and industrial instrumentation circuits. Internally, the part combines a differential input pair with a class-A/AB output stage that delivers rail-to-rail output swing close to the supply limits at light to moderate loads. Typical applications include low-side current sensing with shunt amplifiers, audio preamplifier and mixer stages, active filters for sensor signals, comparators and threshold detectors, bridge and strain-gauge instrumentation, relay and solenoid drive feedback, and general industrial control signal conditioning. The wide 32 V supply ceiling also suits 24 V industrial bus rails that need headroom for transients. One key design consideration is that the 1 MHz gain-bandwidth product limits closed-loop bandwidth to roughly the gain-bandwidth divided by the noise gain. Use a current-feedback or faster rail-to-rail device when the signal bandwidth exceeds roughly 100 kHz at higher closed-loop gains, and keep layout short to avoid parasitic capacitance on the inverting input that can destabilize the amplifier. This page consolidates manufacturer feature data, pin-level detail, drop-in replacement options, and practical layout guidance so that engineers can qualify the LM2904DR2GH for both new designs and repair or obsolescence-driven redesigns.

LM2904DRE4

LM2904DRE4 - Dual 700kHz Op Amp | Texas Instruments

Texas Instruments LM2904DRE4 is a dual, general-purpose operational amplifier in an 8-pin SOIC package. It operates from a single power supply or from split supplies, supports supply voltages up to 26 V, and provides a gain-bandwidth product of 700 kHz. The device contains two independent operational-amplifier channels and is intended for cost-sensitive applications that require an industry-standard, widely available amplifier. An operational amplifier is an analog signal-conditioning integrated circuit whose differential input and high open-loop gain allow it to amplify, buffer, filter, compare, or drive external circuits. The LM2904 belongs to the operational-amplifier hierarchy within amplifier ICs and power-semiconductor devices. Its two channels can amplify different signals in one package while sharing common supply pins, making it useful where board area and external component count are important. The 700 kHz gain-bandwidth product is the principal dynamic parameter identified for the LM2904 family. It determines the useful bandwidth for closed-loop amplifier configurations and affects how quickly the output can respond to input-voltage changes. The manufacturer lists a slew rate of 0.3 V/us for the LM2904DRE4, another indication that the device is optimized for general-purpose analog signal processing rather than high-speed data acquisition. The LM2904DRE4 is specified for operation with a maximum total supply voltage of 26 V. This allows use in conventional 5 V, 12 V, and 24 V industrial systems when the absolute maximum voltage and common-mode operating limits are respected. Its supply-current drain is characterized as low and independent of supply voltage, while the common-mode input range includes ground, which is important in single-supply sensor and control circuits. Typical applications include low-cost sensor conditioning, audio preamplification, general-purpose filtering, comparators with suitable output pull-up arrangements, and two-channel industrial control. The dual-channel format is especially useful for portable instruments, sensor interfaces, audio boards, and educational electronics where one package provides two independent amplifier sections. Design with the LM2904DRE4 using the pin-description table and recommended operating conditions in the manufacturer datasheet. Pay particular attention to input common-mode voltage, output swing, supply polarity, input bias current, and stability requirements. Decoupling capacitors should be placed close to the supply pins, and sensitive analog inputs should be routed away from switching nodes and high-current return paths. This product page combines the manufacturer’s core electrical ratings with practical application guidance, package information, and a same-package replacement comparison. It also distinguishes the standard dual LM2904 ordering options from automotive, revised, and cross-brand equivalents, helping engineers assess footprint compatibility before committing to a PCB substitution.

LM2904DRG3 - Dual 26 V, 700 kHz Op Amp | Texas Instruments
LM2904DRG3

LM2904DRG3 - Dual 26 V, 700 kHz Op Amp | Texas Instruments

Texas Instruments LM2904DRG3 is a dual, general-purpose operational amplifier with two independent amplifiers, a 26 V supply rating, a 700 kHz gain-bandwidth product, and an 8-pin SOIC package. The device supports single-supply or split-supply operation and is intended for general-purpose signal conditioning where a wide operating-voltage range and conventional micropower consumption are useful. An operational amplifier is a voltage-feedback amplifier that uses high open-loop gain to amplify the difference between its inverting and non-inverting inputs. Operational-amplifier ICs sit within the broader amplifier hierarchy and are widely used in analog signal chains for sensing, buffering, filtering, comparison, and closed-loop control. The LM2904 contains two frequency-compensated amplifiers, allowing one package to serve two independent analog functions. The LM2904 provides a 700 kHz gain-bandwidth product, 0.3 V/us typical slew rate, and approximately 0.7 mA typical supply-current drain. Its common-mode input range includes ground, which makes it useful in single-supply applications that process signals near the lower supply rail. The 26 V maximum supply rating provides additional operating headroom for industrial and automotive-style circuits when the board is otherwise designed for lower voltages. Each amplifier is frequency compensated and intended for general-purpose closed-loop operation. Its approximately 700 kHz gain-bandwidth product supports signal paths that do not require the bandwidth of modern precision or high-speed amplifier families. The dual configuration can implement two amplifiers per package, reducing board area in designs such as sensor conditioning, active filtering, error amplifiers, and low-frequency control loops. The 8-SOIC package is also a practical option for through-hole assembly processes. Typical applications include low-frequency sensor signal conditioning, active filters, audio preamplifier stages, battery-powered instrumentation, and industrial control interfaces. In a typical application, the amplifier is configured with external feedback resistors or capacitors, while the non-inverting input receives the sensor or reference signal. Single-supply operation is especially useful when the input signal remains close to ground and a negative supply is undesirable. Designers should verify the input and output common-mode limits across the intended supply voltage and load current, and should use suitable bypassing capacitors near the power pins. Stable operation also depends on following the recommended feedback-network values and ensuring the source and load impedances do not compromise gain, noise, or phase margin. The 8-SOIC footprint leaves adequate routing space for conventional external compensation or gain-setting components where needed. This page combines the manufacturer product information with practical package, sourcing, replacement, and design guidance. It highlights the LM2904DRG3's useful balance of dual-channel integration, wide supply range, conventional bandwidth, and assembly compatibility for cost-conscious general-purpose analog designs.

LM2904DRG4

LM2904DRG4 - Dual 26V 700kHz Op Amp | Texas Instruments

Texas Instruments LM2904DRG4 is a dual, general-purpose operational amplifier with a 26 V supply rating, 700 kHz gain-bandwidth product, and 8-pin SOIC package. The device contains two independent, internally frequency-compensated amplifiers intended for cost-sensitive systems that require reliable operation from single or dual supplies. Its 8-SOIC package is supplied tape-and-reel under the DRG4 ordering suffix. An operational amplifier is an analog signal-processing IC that compares voltages applied to its high-impedance differential inputs and drives its output to amplify the difference between them. Within the broader semiconductor hierarchy, an operational amplifier belongs to the amplifier IC and linear IC categories. The LM2904 combines two amplifiers in one package, allowing a circuit to implement two signal-processing channels without using two separate single-amplifier packages. The LM2904 provides 700 kHz gain bandwidth and a typical slew rate of 0.3 V/µs. Its single-supply current drain is approximately 0.7 mA per amplifier and is described as independent of supply voltage. The common-mode input range includes ground, while the device supports high-voltage operation for industrial, automotive, and control-system applications. These characteristics make it appropriate for general signal conditioning, feedback control, buffering, and low-to-moderate-frequency analog systems. Each amplifier is independent and internally frequency compensated, simplifying circuit design because an external compensation network is not required for ordinary closed-loop operation. The wide supply capability also allows operation from a single supply or from positive and negative rails. Designers should still verify common-mode range, output swing, input bias behavior, and stability against the specific supply voltage used in the final application. Typical uses include industrial process-control loops, transducer-signal conditioning, audio and communications-channel amplification, sensor interfaces, and low-frequency feedback systems. In a control application, the amplifier can close a feedback loop around an actuator or sensor stage. In signal conditioning, it can amplify a sensor voltage while preserving the common-mode range permitted by the selected power rails. A key design consideration is that the 8-SOIC footprint requires conventional surface-mount assembly and careful handling of input bias current and common-mode limits. Decoupling capacitors should be placed close to the supply pins, and sensitive input traces should be kept away from switching nodes. Input and output voltages must remain within the limits stated in the manufacturer datasheet. This page organizes the verified device information, sourcing routes, and engineering considerations into a practical component-selection reference. It also identifies any missing electrical details explicitly so engineers can consult the pin-description and electrical-characteristics tables before releasing a design.

LM2904DT - Dual 1.1MHz General Purpose Op Amp | STMicroelectronics | SOIC-8
LM2904DT

LM2904DT - Dual 1.1MHz General Purpose Op Amp | STMicroelectronics | SOIC-8

The STMicroelectronics LM2904DT is a low-power dual general-purpose operational amplifier providing two independent, internally frequency-compensated amplifiers in an 8-pin SOIC (SOP-8) surface-mount package, with a 1.1 MHz unity-gain bandwidth and single-supply operation for automotive and industrial control systems. An operational amplifier (op amp) is a high-gain differential amplifier that compares an inverting and a non-inverting input and drives its output to amplify the difference between them. When the frequency compensation network is integrated on-chip, the part is called internally compensated and is stable at unity gain without external components. The dual configuration places two independent amplifiers in a single 8-SOIC body, roughly halving the footprint compared with two discrete single amplifiers. In the product hierarchy the device sits as an operational amplifier within analog amplifier ICs and, in turn, within integrated circuits. Key features include two independent channels in one 8-SOIC package, a 1.1 MHz gain-bandwidth product, internal frequency compensation that removes external compensation parts, a low power supply drain that is independent of the magnitude of the output voltage swing, and single-supply operation over a wide voltage range. The LM2904 family was designed specifically for automotive and industrial control systems, so robustness and supply-voltage tolerance matter more than precision offset or ultra-low noise. Internally the device uses a classic internally compensated bipolar input stage with single-ended outputs. Both amplifiers share one supply rail and one ground reference, so bypass and grounding rules apply to the whole package: place a small ceramic capacitor adjacent to the supply pin and add local bulk decoupling near the pins. Output swing is not rail-to-rail, so the load must be chosen so the output stays inside the supply range, and the input common-mode range must be respected when signals approach the rails. Typical uses include motor and solenoid feedback loops in automotive electronic control units, industrial sensor signal conditioning, bridge and transducer amplification, low-side current sensing, and general DC buffering inside PLC and instrumentation racks. Two independent channels in one package also serve a control loop and a monitoring channel together. One design tip: keep feedback routing short, guard high-impedance input nodes against pickup, and decouple the supply at the package. Do not select this amplifier where rail-to-rail input or output, very low noise, or micro-power operation is required; choose a precision or CMOS-input amplifier family instead. This page combines the manufacturer specification summary, a complete pin map for the SOIC-8 footprint, drop-in alternatives with quantified parameter differences, and practical power, layout, and signal-integrity notes that are not combined in a single manufacturer document.

It is designed for low power drain, common-mode input operation extending toward ground or VEE, and use with either a single supply or split supplies. These characteristics make it suitable for battery-operated instrumentation, sensor signal conditioning, audio and communication circuits, and general analog control systems where two independent amplifier sections are required. An operational amplifier is an analog integrated circuit that uses high-gain differential amplification with negative feedback to create stable, controlled gain. The dual-amplifier configuration combines two amplifier sections in one package, reducing board area compared with two separate single amplifiers. Its common-mode input range extending toward ground or VEE is particularly useful in single-supply systems, where signals may be referenced close to the lower supply rail. The LM2904EDR2G is positioned as a low-power, general-purpose amplifier rather than a high-speed or precision device. Its dual-channel architecture supports independent signal paths within one package, while single-supply or split-supply operation allows integration into both grounded and bipolar-style signal chains. The 8-SOIC package provides a familiar surface-mount footprint suitable for conventional PCB assembly. The LM2904 family derives its circuit design from the same basic architecture used in quad operational amplifiers, with the LM2904 providing two amplifier sections. This family positioning supports familiar design conventions and makes the device relevant to applications previously addressed by discrete or multi-package amplifier arrangements. Exact input offset, bandwidth, current, noise, and voltage-limit figures should be confirmed against the manufacturer datasheet for the selected operating condition. Typical applications include DC sensor amplification, low-side current sensing, audio preamplification, industrial signal conditioning, temperature-measurement circuits, and portable equipment powered from a single battery. In each case, the dual section can process two related or independent channels while operating close to the lower supply rail. Decoupling and grounding remain important because they directly affect stability and measured signal quality. For PCB implementation, place the device power pins and input and output traces according to the manufacturer pin-description table. Use a stable reference ground, route sensitive input lines away from switching nodes, and provide local supply bypassing to limit disturbance reaching the amplifier. Verify the final circuit against minimum gain, output swing, slew rate, and common-mode limits before production. This product page combines the exact ordering information with practical guidance for dual-amplifier selection, pinout use, power-rail planning, and replacement assessment. It also identifies compatible circuit roles and highlights where engineers must verify operating limits rather than assume that every low-power dual amplifier is interchangeable.

The device is specified in an 8-pin SOP package and is intended for general-purpose amplifier applications requiring low current consumption, wide operating supply voltage, and input/output common-mode range extending toward ground. The LM2904F-E2 is identified by ROHM as a ground-sense operational amplifier and is not recommended for new designs. A ground-sense operational amplifier is an op-amp configuration designed to measure or amplify small voltage signals referenced to ground, especially signals whose lower operating range is close to 0V. The LM2904 family combines two amplifiers in one package, allowing each channel to be used independently for signal conditioning, buffering, or low-level voltage amplification. Its wide supply-voltage range allows operation from 3V single-supply systems through higher-voltage industrial control and instrumentation circuits. The verified product information identifies the LM2904F-E2 as a standard general-purpose amplifier with two circuits, an 8-SOP package, and a 3V to 32V operating supply range. ROHM's product page also identifies the device as a ground-sense operational amplifier and states that it cannot be used for new designs. The -E2 suffix denotes the manufacturer's ordering or packaging designation, while the F variant identifies the ground-sense amplifier family. Typical uses include current-sense signal conditioning, sensor-interface circuits, low-voltage control systems, and instrumentation in which the input signal can approach the negative supply rail. The dual configuration can reduce board area when two related analog channels are required. The 8-pin SOP package is also compatible with conventional through-hole and leaded assembly processes, although current designs should confirm the availability and lifecycle status of the exact suffix before committing a new production release. Designers should review the manufacturer datasheet for the complete electrical limits, input common-mode behavior, output swing, bias-current specifications, noise values, compensation stability, and recommended decoupling. A stable bypass capacitor should be placed close to the supply pins, and unused input channels should be handled according to the datasheet's recommended configuration. Because the manufacturer does not recommend this part for new designs, engineers should normally evaluate a current recommended dual operational amplifier with the same 8-pin footprint and equivalent electrical performance. This page combines the manufacturer product information, distributor identification, lifecycle notice, package data, and practical engineering guidance for engineers evaluating the LM2904F-E2 or searching for a compatible replacement.

The ROHM Semiconductor LM2904FJ-E2 is a dual ground-sense operational amplifier with two amplifier circuits, a single-supply operating range of 3 V to 32 V, and low current consumption in an 8-SOP-J package. Its input and output ground-sense architecture allows the device to operate near the lower supply rail when the system requires common-mode input and output behavior close to ground. A ground-sense operational amplifier is a voltage-feedback amplifier designed for applications where the signal and output can operate near the negative supply rail. Within the broader hierarchy, the LM2904FJ-E2 is an operational amplifier, an analog amplifier IC, and a member of the power-management and signal-conditioning component category. The dual configuration provides two independent amplifier channels in one package, reducing board area in instrumentation and sensor-interface circuits that require more than one amplification stage. The principal device characteristics are its dual-circuit configuration, 3 V to 32 V single-supply range, low current consumption, and input/output ground-sense operation. The 8-SOP-J construction supports conventional surface-mount assembly. Unlike precision, low-noise amplifier families optimized for very small signals, this device is positioned as a general-purpose ground-sense amplifier for cost-conscious industrial and instrumentation designs. The LM2904FJ-E2 can be placed in non-inverting or inverting signal-conditioning configurations, subject to the stability, input-range, and output-swing limitations described by the manufacturer datasheet. Its broad supply range permits operation from low-voltage systems or from a 24 V industrial rail when the relevant device and package ratings permit. The dual architecture is useful when a design needs paired gain stages, buffering, or independent channels. Typical applications include current-sense amplifier interfaces, low-side sensor conditioning, industrial control modules, battery-powered instrumentation, and measurement systems referenced near ground. In each case, the ground-sense characteristic can reduce output-swing constraints that would otherwise limit a conventional amplifier at low signal levels. The exact input and output ranges should be checked against the operating voltage before finalizing the signal chain. PCB design should preserve the manufacturer's recommended bypass capacitance and account for the common-mode and output-swing limits of the selected operating point. Input and output routing should be short, with the ground reference returned cleanly to the device ground pin. Breadboard or long-trace layouts can introduce coupling and stability problems that do not appear in compact, well-decoupled production layouts. This page combines the confirmed device identity, electrical characteristics, package information, application guidance, sourcing workflow, and engineering checks for LM2904FJ-E2. It is intended to help engineers determine whether the dual ground-sense topology fits a specific PCB before ordering, while clearly separating confirmed specifications from values that must be confirmed in the manufacturer datasheet.

LM2904FV-E2 - Dual Ground-Sense Op Amp, 3-32V | ROHM
LM2904FV-E2

LM2904FV-E2 - Dual Ground-Sense Op Amp, 3-32V | ROHM

ROHM LM2904FV-E2 is a dual ground-sense operational amplifier designed for low-current consumption and single-supply operation over a 3 V to 32 V range. The device contains two amplifier channels in an 8-pin SSOP-B package and supports input/output common-mode operation close to ground. These characteristics make it suitable for low-side current sensing, battery monitoring, portable instrumentation, and control systems where the measured signal is referenced to ground. A ground-sense operational amplifier is an analog amplifier optimized for signals near the supply-ground rail. In the broader semiconductor hierarchy, an operational amplifier is a linear amplifier IC used to amplify voltage differences, and a ground-sense amplifier adds input and output common-mode characteristics suited to low-side sensing. It can therefore process small signals without requiring a negative supply rail when the input and output remain within the specified common-mode range. The LM2904FV-E2 provides two independent amplifier channels, low current consumption, and a wide operating supply range. Its ground-sense architecture supports signal acquisition in circuits where one input is close to 0 V and the other input represents a small voltage change. The 8-pin SSOP-B format also provides a compact surface-mount option for industrial and consumer control equipment. ROHM identifies the LM2904FV family as not recommended for new designs, so the device is primarily appropriate for maintenance, repair, and continuation of an established design. Internally, the dual amplifier combines two standard operational-amplifier channels with ground-sense capability and a common supply architecture. The two channels can amplify related measurements, such as two halves of a differential signal, or operate independently when each channel has its own feedback network. The wide 3 V to 32 V supply span permits use from low-voltage battery-powered systems through industrial control rails without requiring a separate low-voltage regulator for the amplifier itself. Typical uses include low-side shunt-current measurement, battery-voltage monitoring, sensor-interface circuits, industrial process controls, and portable test equipment. In a low-side current-sense design, the shunt produces a small voltage proportional to current; the amplifier boosts that differential signal while its ground-sense behavior supports operation near the lower rail. The dual configuration can also provide signal conditioning for paired sensors or implement two independent gain stages. Designers should verify the exact input and output common-mode limits, output-current capability, input-bias current, offset voltage, and noise specifications against the manufacturer datasheet before fixing gain or bias networks. Input bias-current error can be significant when sensing very low-resistance shunts, so resistor values should be selected to balance bias error against bandwidth and stability. Decoupling capacitors should be placed close to the supply pins, and the unused channel should be configured according to the datasheet rather than left floating. This product page combines the manufacturer lifecycle status with package, voltage, and application information, while also providing procurement guidance, comparison structure, and practical engineering notes. Those additions help engineers evaluate whether the established LM2904FV-E2 fits a legacy or maintenance design and what electrical and PCB checks are required before substitution.

LM2904FVJ-E2 - Dual 3-32V Ground-Sense Op Amp | ROHM
LM2904FVJ-E2

LM2904FVJ-E2 - Dual 3-32V Ground-Sense Op Amp | ROHM

The ROHM Semiconductor LM2904FVJ-E2 is a dual ground-sense operational amplifier designed for two independent amplifier channels, a 3 V to 32 V single-supply operating range, and an 8-pin TSSOP-BJ package. Its input and output common-mode range extends to ground, making it suitable for low-side sensing and signal-conditioning systems whose signals remain close to the negative supply rail. A ground-sense operational amplifier is a voltage-feedback amplifier intended to amplify or buffer signals near 0 V without requiring a dual supply. The LM2904FVJ belongs to the broader operational-amplifier hierarchy: voltage-feedback amplifier, analog signal-conditioning IC, and semiconductor. Its rail-to-rail input-and-output ground-sense capability is especially useful in battery-powered monitoring, industrial sensing, and portable equipment where the signal may approach the lower supply limit. The device provides two amplifier channels in one package, reducing board area compared with two separate single amplifiers. Its wide 3 V to 32 V operating range accommodates low-voltage systems as well as higher-voltage industrial supplies. The manufacturer describes low current consumption and ground-sense operation as principal characteristics. Because both channels share one package, designers must also evaluate common supply impedance, thermal behavior, output-current sharing between independent loads, and the maximum load conditions of each amplifier. The LM2904FVJ-E2 is categorized as a standard general-purpose amplifier, but its ground-sense architecture is important in applications where the measured voltage can approach 0 V. Unlike a conventional rail-to-rail amplifier selected only by input common-mode limits, this device specifically addresses ground-referenced input and output operation. The TSSOP-BJ package offers a compact surface-mount format, although careful pin placement and decoupling remain necessary to minimize noise and ground-offset errors. Typical uses include low-side current detection, battery monitoring, portable instrumentation, industrial transducers, sensor interfaces, and low-voltage control systems. In a current-sense application, the amplifier can sit on the low side of a shunt, preserving a ground-centered measurement signal while reducing the voltage burden imposed on the measured circuit. In sensor systems, the close-to-ground input capability reduces the need for an additional offsetting supply. Design around the manufacturer pinout and place input, output, and decoupling connections to minimize parasitic resistance in the feedback network. Maintain short ground-return paths and decouple the supply close to the device. Because the manufacturer classifies this product as not recommended for new designs, new production projects should normally use a currently recommended amplifier unless the legacy footprint, supply range, ground-sense behavior, and electrical performance are mandatory. This page combines the exact manufacturer lifecycle position, package and supply information, drop-in alternatives, application guidance, and design cautions for engineers maintaining or replicating an existing LM2904FVJ-E2-based design. It emphasizes practical selection limits rather than treating the legacy part as a universal modern replacement.

LM2904FVM-GTR - Dual Ground-Sense Op Amp | ROHM

The ROHM Semiconductor LM2904FVM-GTR is a dual ground-sense operational amplifier designed for general-purpose signal conditioning. It provides two amplifier channels in an 8-MSOP surface-mount package, operates from a single supply of 3 V to 32 V, and combines a wide input-voltage range with low current consumption. The -GTR ordering code identifies tape-and-reel production handling. An operational amplifier is an analog amplifier IC that uses feedback to amplify the difference between two input voltages. The dual configuration integrates two amplifier channels into one package, reducing board area in designs that need more than one amplification stage. Within the broader semiconductor hierarchy, an operational amplifier belongs to the amplifier IC and linear IC families, where it supports precision control, measurement, buffering, and signal-conditioning functions. The ground-sense architecture is suited to circuits that monitor or condition signals referenced toward ground. The two independent channels can be used separately or together in applications such as current-sense amplifiers, low-side sensing, sensor interfaces, and general feedback-control blocks. The 3 V to 32 V single-supply range permits operation from compact 3 V systems through substantially higher industrial supply rails, provided the complete circuit remains within the device operating limits. Low current consumption makes the LM2904FVM useful in designs where the amplifier must coexist with battery-powered, portable, or broadly distributed sensing circuitry. Its MSOP-8 package supports compact surface-mount assembly, while the dual channel count reduces the number of packages needed compared with two single operational amplifiers. Engineers should still verify output-current demand, input common-mode range, output swing, noise, offset, and stability requirements against the manufacturer datasheet for the intended application. Typical uses include amplifying the voltage across a low-side shunt, conditioning resistive sensor outputs, and providing gain around analog-control loops. The amplifier can also serve as a buffer when its input bias and noise characteristics meet the system requirements. In each circuit, resistor values should establish suitable gain while keeping the operating point within the device input and output ranges. For PCB implementation, place the device close to the signal source and receiver to minimize susceptibility to noise and parasitic loading. Keep high-current switching paths away from input and feedback nodes, provide a stable decoupling capacitor at the supply pins, and route the feedback loop compactly. Confirm stability with the selected gain and output-load configuration rather than assuming that a generic compensation arrangement fits every application. This page organizes the LM2904FVM-GTR for engineers evaluating dual ground-sense amplifier requirements, including its 3 V to 32 V supply range, 8-MSOP format, use cases, sourcing considerations, and the engineering checks needed before committing a PCB footprint.

LM2904ITP/NOPB - Dual 26V 700kHz Op Amp | Texas Instruments

The Texas Instruments LM2904ITP/NOPB is a dual, general-purpose operational amplifier with a 26 V maximum supply voltage and a 700 kHz rated operating bandwidth, supplied in an 8-DSBGA package. The ordering suffix identifies the tape-and-reel configuration. Its two amplifier circuits, 1 MHz gain-bandwidth product and 0.1 V/us slew rate place it in the classic low-power, general-purpose operational-amplifier category. An operational amplifier, or op amp, is a voltage-controlled differential amplifier intended to amplify the difference between two input voltages. It belongs to the amplifier IC hierarchy, within the broader semiconductor and analog signal-processing categories. A dual op amp combines two amplifier channels in one package, allowing a circuit to implement two signal-processing functions while reducing board area and the number of external components. The LM2904ITP/NOPB is identified as a standard general-purpose amplifier. The listed electrical characteristics include a 26 V maximum supply voltage, 700 kHz operating bandwidth, 1 MHz gain-bandwidth product and 0.1 V/us slew rate. These values position the device for moderate-frequency signal handling rather than high-speed precision work. The 8-DSBGA package also gives PCB designers a compact option for dual-channel analog circuits. The device belongs to the long-established LM2904 family and is associated with the LM158-series operating-amplifier architecture, consisting of two independent, high-gain, internally frequency-compensated amplifiers designed for single-supply operation over a wide voltage range. Internal frequency compensation removes the need for an external dominant-pole capacitor in typical closed-loop configurations, simplifying implementation and stabilizing operation across supported gain settings. Typical uses include low-frequency sensor conditioning, audio preamplification, instrumentation, active filtering, and general dual-amplifier analog signal chains. The dual-channel configuration is particularly useful when a design needs symmetric gain stages, a voltage follower alongside a signal amplifier, or two related sensor interfaces sharing one compact package. Designers should verify the exact input common-mode range, output swing, input offset, input-bias current, supply-current behavior and temperature limits against the manufacturer datasheet before finalizing a circuit. Place the 8-DSBGA on a PCB layout that separates input, output and supply paths appropriately, and use suitable bypassing capacitance at the power pins. Because the package is a fine-pitch BGA rather than a leaded package, assembly capability and land-pattern compatibility also require verification. This product page organizes the confirmed ordering, package, electrical, and commercial information while distinguishing documented LM2904-family options from unconfirmed substitutions. It also provides application guidance, comparison fields, and a pinout limitation notice so engineers can make a package-aware sourcing decision without assuming that every electrically similar dual op amp is a true drop-in replacement.

It operates from a 2.7 V to 5.5 V supply, provides a 1 MHz gain-bandwidth product, and is specified with a 3 mV input offset voltage. The device is supplied in an 8-VSSOP package and provides two amplifier circuits in one package. An operational amplifier is an analog integrated circuit that uses high-gain differential amplification to compare an inverting input with a non-inverting input. Within the broader hierarchy, it is a voltage-feedback amplifier, an amplifier IC, and a signal-conditioning semiconductor. The dual configuration allows one device to process two related channels, reducing board area when both channels share the same supply and ground reference. The LM2904LV-Q1 family targets automotive and industrial low-voltage applications where supply efficiency, cost, and dependable operation are important. The 2.7 V to 5.5 V operating range supports systems powered from regulated 3.3 V and 5 V rails. Its 1 MHz bandwidth makes it suitable for general-purpose amplification, buffering, voltage comparison, filtering, and sensor-interface functions rather than high-speed signal processing. The dual amplifier architecture is useful in sensor conditioning, current sensing, control loops, line-driver buffers, and automotive body electronics. Each amplifier can be used independently, allowing the two channels to monitor complementary signals or perform separate functions in a compact circuit. Input and output stability, common-mode range, and output-drive capability should be checked against the actual signal levels and load conditions. The principal design trade-off is that this is a general-purpose, low-voltage amplifier rather than a precision or high-speed device. Its 3 mV offset specification is appropriate for many sensing and control paths, but systems requiring tighter offset accuracy need to evaluate the bias current, input voltage range, noise, and application error budget. This page combines the manufacturer specifications, package information, application guidance, comparison parameters, and practical drop-in selection notes for engineers evaluating the LM2904LVQDGKRQ1.

The Texas Instruments LM2904M is a dual, general-purpose operational amplifier with a 26 V supply rating, 700 kHz gain-bandwidth product, and an 8-SOIC package. According to the Texas Instruments LM2904 product page, the device is intended for low-power analog signal-processing systems where two amplifiers are useful in a single package. The verified distributor listing identifies LM2904M as a standard two-circuit amplifier in an 8-SOIC package, and the Mouser result specifies the operating-temperature range as -40 °C to 85 °C. An operational amplifier is an analog integrated circuit that uses feedback to amplify the difference between its non-inverting and inverting inputs. The LM2904M belongs to the broader operational-amplifier, analog-amplifier, and semiconductor hierarchies. In practical circuits, each internal amplifier can serve as an inverting amplifier, non-inverting amplifier, comparator, buffer, or integrator when operated with suitable external components and supply voltages. The 26 V supply rating provides compatibility with conventional industrial and analog signal ranges, while the 700 kHz gain-bandwidth product supports low-to-moderate-frequency signal amplification. The dual configuration reduces package count when a circuit needs two amplifier channels. Its general-purpose designation indicates broad applicability rather than a specialized low-noise, high-speed, precision, or automotive-only function. The LM2904M uses an 8-SOIC surface-mount package, corresponding to the soic-8 package library key. The verified results do not provide a complete electrical specification table in the supplied excerpts, so detailed parameters such as input offset voltage, input bias current, slew rate, output-current capability, common-mode range, quiescent current, and noise values are marked as data needed rather than estimated. Typical applications include low-frequency analog signal conditioning, instrumentation interfaces, sensor buffers, audio preamplifier stages, and general dual-amplifier circuits. The dual channel can also be used for active filtering or control loops where two matched functional amplifier sections are useful. Because the available information is general-purpose and distributor-oriented, the designer should verify operating-point limits, loading, stability, and temperature margin against the manufacturer datasheet before release. For PCB implementation, place bypass capacitors close to the supply pins and route sensitive input and feedback traces away from switching nodes and high-current paths. Confirm the exact pin orientation and electrical limits before assembly.

The Diodes Incorporated LM2904M8-13 is a dual general-purpose operational amplifier with two independent amplifier channels, a 700 kHz gain-bandwidth product, 2 mV input offset voltage, and an 8-MSOP package. It operates from a single supply between 3 V and 36 V, while split-supply operation is also supported. The device is characterized for industrial temperatures from -40°C to +125°C and uses green mold compound as standard. An operational amplifier is an analog signal-conditioning IC that amplifies the voltage difference between its inverting and non-inverting inputs. Operational amplifiers belong to the amplifier IC hierarchy and are widely used in sensor interfaces, filters, comparators, feedback-control loops, and low-frequency signal-processing circuits. The LM2904 combines two operational amplifiers in one compact surface-mount package, reducing board area compared with separate single-channel devices. Each LM2904 channel provides high open-loop gain and a 700 kHz gain-bandwidth product. The 2 mV input offset rating helps limit output error in DC amplifier and comparator circuits. Single-supply operation from 3 V to 36 V makes the device suitable for industrial control, instrumentation, sensor-conditioning, and power-supply feedback applications. Its -40°C to +125°C characterization also supports designs operating across extended temperature ranges. The LM2904 architecture supports both single-supply and split-supply operation. In a single-supply circuit, the input common-mode range, output swing, and bias arrangement remain important design constraints, particularly when signals remain close to ground. With dual supplies, the two amplifier channels can process signals around ground more naturally, although common-mode and output-range checks remain necessary at the supply limits. Typical uses include transimpedance amplifiers for low-frequency sensor signals, active filters for analog signal conditioning, threshold detectors, and closed-loop control amplifiers. The two channels may also be configured as a comparator, voltage follower, or differential amplifier, depending on the feedback network and system voltage requirements. Its 8-MSOP package is suited to compact industrial and embedded control boards where a dual amplifier offers practical space savings. For reliable layout, place input and feedback components close to their corresponding pins and keep sensitive input traces away from high-current switching paths. The power-supply pins require effective bypassing with a short ground return. Confirm that input and output signal levels remain inside the amplifier's usable common-mode and output ranges, particularly in single-supply configurations where the available signal headroom is reduced.

LM2904MX - Dual 26V 700kHz Operational Amplifier | TI

Texas Instruments LM2904MX is a dual, general-purpose operational amplifier designed for operation from a single supply across a wide voltage range. The device contains two independent, internally frequency-compensated amplifiers in an 8-pin SOIC package. According to the manufacturer product page, the LM2904 family supports supply voltages up to 26 V and offers a gain-bandwidth product of 700 kHz. Its internally compensated architecture simplifies stable operation as a unity-gain buffer, while its high open-loop voltage gain and low-power design make it suitable for general signal-conditioning tasks. An operational amplifier is a high-gain analog building block used to amplify voltage differences, buffer inputs, perform comparisons, drive external loads, and implement active filters. Within the broader semiconductor hierarchy, the LM2904MX belongs to the operational-amplifier family, which falls under analog ICs and signal-conditioning semiconductors. Unlike precision or rail-to-rail amplifiers, the LM2904 is intended primarily for conventional supply-based operation and general-purpose applications. The principal features of the LM2904MX include two amplifier channels, an 8-SOIC package, a 700 kHz gain-bandwidth product, and operation from a single supply as high as 26 V. The device is internally frequency compensated, which allows operation at unity gain without an external compensation network. A typical slew rate is 0.3 V/us, making the amplifier appropriate for low-frequency analog processing rather than high-speed signal conditioning. The dual configuration also provides cost and board-area efficiency when a design needs two independent amplifier functions. Each channel can support feedback-based amplifier configurations such as non-inverting amplifiers, inverting amplifiers, voltage followers, summing circuits, and active filters. The LM2904MX is useful when signals must be conditioned with external resistors or capacitors and the application does not require the very low offset, low noise, high speed, or rail-to-rail input and output behavior associated with more specialized amplifier families. Its wide supply-voltage capability also permits operation from industrial-style elevated rails, subject to the device ratings. Typical applications include industrial control and instrumentation, sensor signal conditioning, power-supply feedback monitoring, audio and communications interface circuits, active filtering, and general-purpose analog buffers. In a 24 V industrial system, the 26 V maximum supply rating leaves little margin for transient overshoot, so input protection and rail clamping should be considered. The dual channels can serve separate signal paths, but designers should not assume that the two amplifiers share an output or that short-circuit protection makes unlimited current available. Design attention should focus on the input common-mode range, output swing, output-current capability, stability with the intended load, and the power dissipation created by the supply-to-output voltage difference. Place the device close to feedback and bypass components, use a local supply bypass capacitor, and route high-impedance input nodes with minimal parasitic capacitance. Verify operation across supply voltage, temperature, output load, and source resistance because these conditions affect common-mode range, output swing, and amplifier stability. This page combines manufacturer specifications, package details, drop-in alternatives, application guidance, and design checks to support component selection and PCB implementation. It also highlights the distinctions between the LM2904MX and commonly encountered LM2904 order codes so engineers can confirm electrical behavior, package compatibility, and assembly requirements before approving a replacement.

An operational amplifier is an analog integrated circuit that uses high open-loop gain to amplify the difference between two input voltages. Internally compensated LM2904N amplifiers are voltage-amplifier building blocks within the operational-amplifier, analog IC, and semiconductor hierarchies. Their differential inputs support filtering, buffering, summing, comparison, and feedback-control functions without requiring an external compensation network. The verified product information identifies two amplifiers, single-supply or split-supply use, low power drain, and a common-mode input range extending to ground or VEE. Its internally frequency-compensated architecture simplifies closed-loop design, while the dual configuration places two matched-function amplifiers in one package. However, the supplied data does not state output-current capability, input-offset voltage, input-bias current, slew rate, noise density, or operating-temperature limits. A key design consideration is supply configuration. Although the official TI product-page snippet specifies a 26 V product family designation, engineers must consult the exact manufacturer datasheet before setting rail voltage, input common-mode limits, output swing, and load current. Decoupling capacitance, input impedance, feedback topology, output loading, and thermal dissipation also remain datasheet- and layout-dependent. Typical uses include two-channel sensor conditioning, low-frequency active filters, audio preamplification, comparator-style signal detection with suitable saturation limits, control-loop buffering, and general dual-rail analog signal processing. The 1 MHz bandwidth is most appropriate for low-to-moderate-frequency signals rather than high-speed precision instrumentation.

According to the Texas Instruments product page, the device is a standard dual operational amplifier rather than a low-noise or precision amplifier. An operational amplifier is an analog integrated circuit that uses high open-loop gain to amplify the difference between two input voltages. In a closed-loop configuration, external feedback components define the gain, bandwidth, filtering, and signal behavior. The LM2904P belongs to the broader hierarchy of operational amplifier, analog amplifier, and semiconductor, while its dual configuration saves board area by placing two amplifiers in one package. The verified manufacturer information identifies a maximum 26 V supply-related range and 700 kHz performance. The package is 8-PDIP. Texas Instruments describes the LM2904 as an industry-standard dual operational amplifier family, but the supplied verified data does not include a complete electrical parameter table. Consequently, input offset voltage, input bias current, output current, noise, common-mode range, slew rate, operating temperature, and exact electrical limits are marked as data needed rather than inferred. LM2904P circuits are commonly considered for sensor amplification, buffered analog signals, low-frequency active filters, and general-purpose control loops. Because it is a standard dual amplifier in a through-hole package, it is especially useful for prototypes, educational boards, legacy equipment, and industrial control systems where DIP packaging simplifies manual assembly and inspection. The second amplifier can mirror the first stage, provide filtering, buffer an output, or implement another independent channel. Designers should verify supply polarity, input common-mode limits, output swing, stability with the selected load, and capacitor values against the full manufacturer datasheet before production use. Decoupling capacitors should be placed close to the supply pins, and feedback components should be kept compact to reduce parasitic capacitance. If low-noise, rail-to-rail input/output, high-frequency, or automotive-qualified performance is required, a different amplifier family should be selected after reviewing the complete electrical data.

The LM2904 belongs to the operational-amplifier hierarchy, which includes voltage-feedback amplifiers, general-purpose amplifiers, instrumentation amplifiers, and precision amplifiers. Two amplifiers in one package can reduce board area when a circuit needs matched functions such as buffering, amplification, filtering, or differential sensing. The verified manufacturer information identifies the LM2904 as a dual, 26 V, 700 kHz operational amplifier. The LM2904P3 orderable is identified as a general-purpose, two-circuit amplifier in an 8-PDIP package. Its dual configuration allows both amplifier sections to share one package while retaining independent inputs and outputs. The 26 V rating permits operation from higher-voltage analog systems than typical low-voltage mixed-signal amplifier families. The 700 kHz gain-bandwidth figure defines the practical frequency range for many small-signal applications. It is relevant when closing an amplifier around a feedback network, because the amplifier must provide adequate loop gain and phase margin at the intended signal frequency. General-purpose performance makes the device suitable for signal amplification, voltage buffering, active filtering, and feedback-control stages where specialized precision or high-speed parameters are not required. Typical uses include industrial sensor interfaces, low-frequency active filters, audio preamplifier stages, analog control loops, and general instrumentation. In a dual-amplifier circuit, one section can perform signal conditioning while the other supplies inversion, feedback, or buffering. The package is also appropriate for through-hole industrial designs where DIP mounting remains preferable to fine-pitch surface-mount assembly. Designers should verify the complete electrical limits, electrical characteristics, pin configuration, common-mode range, output swing, input bias current, slew rate, and stability requirements in the manufacturer datasheet before finalizing a design. Decoupling, input and output signal limits, common-mode voltage, and thermal conditions must be evaluated for the exact operating environment.

LM2904PW - Dual 700 kHz Op Amp, 26 V | Texas Instruments

The Texas Instruments LM2904PW is a dual general-purpose operational amplifier with a 700 kHz gain-bandwidth product, 26 V maximum supply capability, and an 8-pin TSSOP package. The device contains two independent, frequency-compensated amplifiers that can operate from a single supply or split supply, making it suitable for signal conditioning, buffering, and general-purpose analog control applications. Its 0.7 mA typical supply-current drain is specified as being independent of supply voltage, helping conserve power across a broad operating range. An operational amplifier, or op amp, is an analog integrated circuit that uses high open-loop gain to amplify the difference between two input voltages. A dual op amp combines two amplifiers in one package, allowing both channels to share a supply while remaining electrically independent. Within the broader semiconductor hierarchy, the LM2904PW belongs to the amplifier IC, operational-amplifier, analog-signal-conditioning, and integrated-circuit families. It is a widely recognized general-purpose alternative to newer precision and low-noise amplifier families when voltage range, low power, and functional simplicity matter more than low offset or rail-to-rail operation. The principal operating characteristics include a 26 V maximum supply voltage, a 700 kHz gain-bandwidth product, two amplifier circuits, and a typical supply-current drain of 0.7 mA. The common-mode input range includes ground, allowing the device to sense input signals close to the negative supply rail. Low input-bias and input-offset parameters are identified in the device literature, although exact minimum and maximum limits are not included in the retrieved data. The LM2904PW therefore provides a practical balance of gain bandwidth, supply flexibility, and low supply-current demand. Internally, the LM2904 uses a frequency-compensated voltage-feedback architecture. This internal compensation means each amplifier can provide stable closed-loop operation without an external frequency-compensation network when configured for typical noninverting or inverting gains. The design is intended for general-purpose analog systems rather than precision instrumentation. Its 700 kHz gain-bandwidth product is adequate for audio-frequency signal conditioning, low-rate data acquisition, sensor interfaces, and industrial control blocks, but it is substantially slower than precision, high-speed, or rail-to-rail amplifier families. Typical uses include general-purpose signal amplification, low-frequency active filtering, current-to-voltage conversion for sensors, audio preamplification, comparator-style threshold conditioning with suitable output limits, and industrial control interfaces. The ability to operate from single or split supplies makes the part useful in systems whose signal range is referenced to ground. For battery-powered equipment, the typical 0.7 mA supply-current drain helps limit consumption, although the complete system current also depends on output current, load, amplifier configuration, and supply voltage. Designers should verify the exact common-mode, output-swing, offset-voltage, input-bias-current, slew-rate, and temperature limits from the manufacturer datasheet before fixing operating conditions. Input and output stability depends on layout, source impedance, load, and feedback topology. Decoupling should be placed close to the supply pins, and sensitive layouts should minimize parasitic capacitance and leakage around high-impedance inputs. The 8-pin TSSOP footprint is compact but requires careful lead pitch and thermal considerations during assembly. This product record combines the verified manufacturer identity, package, voltage, bandwidth, and power information with distributor pricing and cross-reference evidence. It also adds practical application guidance, honest substitution limits, package-level comparison data, and design notes intended to help engineers evaluate the LM2904PW beyond a raw distributor listing.
