LM2904BIDR - Dual 36V 1.2MHz Op Amp | SOIC-10 | TI

The Texas Instruments LM2904BIDR is an industry-standard dual operational amplifier in an 8-pin SOIC package, delivering 1.2 MHz unity-gain bandwidth and a wide 3 V to 36 V supply range with single-supply operation. It is the next-generation 'B' revision of the legacy LM2904, providing tighter DC accuracy (lower input offset voltage), lower noise, and a 1.2 MHz bandwidth upgrade versus the original 700 kHz device, while remaining in the industry-standard 8-pin SOIC footprint used by all LM358 / LM2904 variants. Each channel is a bipolar voltage-frontier amplifier with internal EMI/RFI filtering and ESD protection on the inputs, and the device operates over the automotive -40C to +125C temperature range. An operational amplifier (op amp) is a high-gain DC-coupled differential amplifier whose output voltage is amplified by an external feedback network to perform amplification, filtering, and signal conditioning. A dual op amp integrates two ICs into a single package and is the same circuit-level topology (LDO) integrated with a higher-level power-supply chain and ultimately a semiconductor device, while dual op amps specifically serve as a low-side companion building block used in many sensor, instrumentation, and power-management signal chains. Key features include 1.2 MHz gain-bandwidth product, 0.5 mV typical (3 mV maximum) input offset voltage, 45 V/us (typical) slew rate, 25 nA input bias current, and an output swing that includes both rails. The device operates on a single supply from 3 V up to 36 V (or dual +/-1.5 V to +/-18 V). It is internally compensated for unity-gain stability and includes short-circuit protection on the output, making it suitable for direct drive of low-impedance loads in industrial and automotive environments. The LM2904BIDR uses a bipolar process with a PNP input stage that supports input common-mode voltages down to ground (and up to VCC - 1.5 V), enabling true single-supply operation from a 5 V or 12 V rail. The dual-channel architecture allows one IC to implement two independent gain stages - commonly a transimpedance amplifier and a buffer, or two channels of a differential sensor front-end - saving PCB area, cost, and complexity versus using two single-channel op amps. Typical applications include transducer interfaces (load cells, strain gauges, pressure and flow sensors), low-side current sensing in motor drives and battery management, active filters and integrators for instrumentation, comparator-like threshold detection, and general-purpose signal conditioning on 12 V / 24 V industrial and automotive buses. The wide supply range and automotive-grade temperature rating make it drop-in compatible with virtually every legacy LM288 / LM358 / LM2904 design. When designing with this device, ensure the input common-mode voltage remains within the linear range (GND to VCC - 1.5 V). For single-supply designs, AC-couple the input or bias the network to mid-supply. Decouple the supply pin with a 1 uF / 100 nF parallel pair within 10 mm of the IC, and avoid driving capacitive loads greater than 1 nF directly - add a series isolation resistor if needed. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet, giving you a complete engineering perspective in one page.

The device is supplied in an 8-pin SOIC package and provides two amplifier channels in one package. Its 0.7 mA typical supply-current draw supports low-power signal-processing systems. An operational amplifier is an analog amplifier that uses high open-loop gain and negative feedback to amplify voltage differences. Within the semiconductor hierarchy, an operational amplifier belongs to the amplifier IC and signal-conditioning category. The LM2904 combines two general-purpose amplifier channels in a single package, reducing board area when a design requires matched dual-channel functions such as filtering, buffering, or gain stages. The LM2904DE4 provides a 700 kHz gain-bandwidth product, a 0.3 V/µs slew rate, and a low 0.7 mA typical supply-current drain independent of supply voltage. Its common-mode input range includes ground, making it useful in circuits that operate near the lower supply rail. The dual configuration supports applications in industrial controls, sensor interfaces, audio paths, and general-purpose analog signal conditioning. The 26 V maximum supply rating provides ample headroom for conventional industrial supply rails, although the actual operating voltage must remain within the manufacturer’s specified limits. Because this is a general-purpose amplifier rather than a precision part, design engineers should verify input offset, input bias current, output swing, and channel behavior against the application’s signal-integrity requirements. Feedback-network components and signal-source impedances determine practical accuracy and stability. Typical uses include two-stage sensor amplification, low-frequency active filters, buffered instrument inputs, audio preamplification, and general industrial signal conditioning. The 8-pin SOIC package is also compatible with conventional surface-mount assembly and automated PCB manufacturing. The dual organization allows one package to implement complementary signal paths while reducing component count compared with two separate single amplifiers. For stable operation, follow the manufacturer’s recommended compensation and decoupling practices, place input and output networks close to the device, and avoid driving the output beyond its specified load and swing limits. Grounding and trace-return paths should be planned to prevent supply and ground noise from entering the signal path. The manufacturer datasheet is the controlling reference for electrical limits, pin functions, and application details. This product page combines the official family specifications with practical design guidance, application fit analysis, and a package-focused replacement comparison. It is intended to help engineers identify the correct operating limits and select a pin-compatible alternative without overlooking differences in bandwidth, slew rate, supply current, or package construction.

onsemi LM2904DG is a dual, general-purpose operational amplifier with two independent amplifiers, 1 MHz gain-bandwidth product, 0.6 V/us slew rate, and a 3 V to 32 V supply range in an 8-pin SOIC package. It supports single-supply or split-supply operation and accepts input common-mode voltages extending to ground and VEE. An operational amplifier is a voltage-controlled differential amplifier used to amplify, buffer, filter, compare, or drive analog signals. The LM2904 belongs to the broader operational-amplifier hierarchy, where the dual configuration provides two signal-processing channels in one package. This makes it useful where board area, component count, and supply flexibility are more important than precision or high speed. Key features include a 1 MHz gain-bandwidth product, 0.6 V/us slew rate, and a minimum common-mode rejection ratio of 50 dB. The device is specified for a 3 V to 32 V total supply, allowing operation from a single positive rail or from positive and negative rails. Its common-mode input range extends to ground and VEE, which supports battery-powered, industrial-control, and sensor-interface designs where input signals may approach the lower supply rail. The input offset voltage is listed at 7 mV, making this amplifier more appropriate for general-purpose amplification than precision instrumentation applications requiring microvolt-level offset. Its moderate gain-bandwidth product and slew rate are appropriate for audio-frequency control loops, slow sensor signals, active filtering, comparators, and general analog signal conditioning. The dual architecture also allows both amplifiers to share the same supply and decoupling network. Typical uses include DC motor and actuator feedback control, transducer buffering, low-frequency active filters, audio preamplification, regulated power-supply feedback, and general-purpose analog interfaces. Split-supply operation can simplify biasing around ground, while single-supply operation helps reduce system power and board complexity in battery-operated equipment. Designers should account for input bias current, output-current capability, common-mode limits, and stability when driving capacitive loads. Place decoupling capacitors close to the supply pins, keep feedback routing compact, and verify output swing against the actual load. For applications requiring very low offset, very wide bandwidth, rail-to-rail output, or automotive qualification, compare the LM2904 family against more specialized amplifier families.

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.

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 - 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 - 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.

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.

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.

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.

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.

LM2904EDR2G - Dual Low-Power Operational Amplifier | onsemi

onsemi LM2904EDR2G is a dual, general-purpose operational amplifier with 2 amplifier channels in an 8-pin SOIC package. 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.

LM2904F-E2 - Dual Ground-Sense Op Amp, 3-32V | ROHM Semiconductor

The ROHM Semiconductor LM2904F-E2 is a dual ground-sense operational amplifier designed for single-supply operation from 3V to 32V. 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.

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.

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.

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 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.

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.

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.

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 a voltage-gain amplifier whose closed-loop behavior is determined mainly by external feedback components. The LM2904 belongs to the dual general-purpose operational-amplifier family, combining two amplifier channels in one package. This integration reduces board area compared with two discrete single amplifiers and simplifies dual-channel designs requiring common supply voltage and similar operating characteristics. The manufacturer identifies the LM2904 as a low-power, dual operational-amplifier family for general-purpose applications. Its 26 V maximum supply rating supports higher-voltage analog systems than many low-voltage rail-to-rail amplifiers, while the 700 kHz gain-bandwidth product provides useful bandwidth for control, sensing, buffering, and signal-conditioning tasks. The 8-SOIC package offers a conventional surface-mount footprint that is practical for both new designs and upgrades of existing 8-pin amplifier boards. The MX ordering code denotes the manufacturer's SOIC package option, while /NOPB identifies the lead-free, non-PB-free finish. The 8-SOIC format is useful for prototypes, repair assemblies, and industrial equipment requiring a stable package outline. Designers should consult the manufacturer datasheet for the complete electrical limits, input/output characteristics, supply-current behavior, compensation information, pin assignments, and recommended operating conditions before releasing a production design. Typical LM2904 applications include two-channel sensor amplification, transducer-signal conditioning, low-frequency active filtering, voltage comparison, analog control loops, and general instrumentation. In these applications, the device can amplify signals from sensors, provide gain around analog front ends, or drive feedback networks when the operating range and load capability meet the circuit requirements. The dual channel can also implement differential or complementary stages where the two amplifiers operate within the same supply system. The primary design consideration is ensuring that the input common-mode range, output swing, supply voltage, noise, offset, and stability remain suitable for the application. Bypass capacitors should be placed close to the supply pins, while input, feedback, and compensation components should be positioned to minimize parasitic capacitance and unwanted feedback. Because the package exposes both amplifier channels, grounding and return-current paths should be planned to avoid coupling between the two signal paths. This product record combines the manufacturer specifications with package details, application-oriented guidance, technical comparison criteria, and verified sourcing references. It also distinguishes genuine same-footprint alternatives from broader functional equivalents, helping engineers make a board-level replacement decision while recognizing that electrical equivalence must be confirmed against the complete manufacturer datasheet.
