LM2904AQM8-13 - Dual 36V Op Amp, 500uA | Diodes

Diodes Incorporated LM2904AQM8-13 is an automotive-compliant, dual operational amplifier packaged in an 8-MSOP. The device operates from a 36 V maximum supply, provides two amplifier channels, and is specified for 500 uA supply current, 20 nA input bias current, and 100 dB open-loop gain. Its 8-MSOP package supports compact analog signal-conditioning layouts while retaining the industry-standard dual-op-amp pin arrangement described for the LM2904Q family. An operational amplifier, or op amp, is a high-gain analog amplifier used to amplify voltage differences, buffer sensors, drive external loads, and implement active filters. The LM2904 belongs to the broader general-purpose amplifier hierarchy, which includes dual and quad operational amplifiers used in signal-chain, instrumentation, and control applications. Its wide supply range makes it useful where signal levels and supply conditions vary substantially. The headline characteristics make the LM2904AQM8-13 appropriate for low-power signal conditioning. A 36 V maximum supply expands the usable operating envelope, while 500 uA supply current limits the power burden of dual-channel circuits. The 20 nA input bias current reduces loading on high-impedance sources, and 100 dB open-loop gain provides useful amplification when feedback establishes the closed-loop gain. The LM2904Q family uses industry-standard pin arrangements and is available in multiple small-outline packages. The M8-13 ordering option places this dual amplifier in an 8-MSOP. For conventional non-unity-gain operation, feedback networks define the closed-loop response, while input common-mode and output-swing limits must remain within the datasheet operating envelope. Decoupling should be placed close to the supply pins to reduce supply-borne noise. Typical uses include low-side current monitoring, transducer and sensor interfaces, buffered analog measurements, active filtering, and general-purpose signal conditioning in automotive or industrial equipment. The dual configuration reduces board area when two independent analog channels are required, although crossover distortion is important when similar signals are amplified simultaneously at high output levels. Designers should verify input bias current, input offset voltage, output swing, common-mode range, and stability requirements against the complete operating conditions. Avoid relying on rail-to-rail operation unless the applicable LM2904 datasheet explicitly confirms the required input or output range. Decoupling capacitors, grounding, and feedback-component placement remain important even though the amplifier itself has a low supply current of 500 uA. This product page consolidates the verified order information, package details, technical attributes, application guidance, and qualified drop-in comparison points. It is designed to help engineers determine whether the LM2904AQM8-13 fits a compact, dual-channel automotive signal-conditioning design and to identify the closest pin-compatible alternatives before a board-level substitution.

The Diodes listing also identifies a 100 dB open-loop gain metric and approximately 500 uA supply-current class, which make the amplifier practical for low- and moderate-frequency industrial and automotive circuits. The LM2904AQ family is identified by Diodes Incorporated as automotive compliant. The S suffix in LM2904AQS-13 identifies the SO-8 package option, while -13 identifies the supplier packaging format. This dual-channel configuration allows one package to implement two independent amplifier stages, reducing component count when a board requires signal buffering, differential amplification, active filtering, or two sensing channels. Typical applications include 5 V and 12 V sensor interfaces, automotive transponder and battery-management signal conditioning, industrial process-control inputs, active low-pass filters, and general dual-amplifier boards. The wide 36 V supply capability is particularly useful where signal nodes can experience industrial transients or automotive battery-related voltages, provided the design keeps every pin within the device's absolute maximum ratings. Design the feedback network for the intended closed-loop bandwidth, keep input and output signals within the common-mode range, and bypass the supply pins close to the package. Decoupling capacitors should be placed at the IC rather than at the power-source entry point. If the amplifier drives capacitive loads, add an isolation resistor and verify stability and output-current margin in the final board layout. This page combines package, electrical, automotive-compliance, cross-reference, and replacement information with practical guidance for dual op-amp layouts. It helps engineers distinguish the exact automotive SO-8 device from broader LM2904 variants, package variants, and functional alternatives that may require different qualification or footprint review.

LM2904ATH-13 - Dual General-Purpose Op Amp | Diodes Incorporated

The Diodes Incorporated LM2904ATH-13 is a dual, general-purpose operational amplifier packaged in an 8-pin TSSOP. It is intended for single-supply or dual-supply signal-conditioning applications and uses the widely recognized LM2904 amplifier architecture. The device operates from a single supply up to 36 V or from split supplies totaling 36 V, equivalent to ±18 V, while providing two amplifiers in one package. The LM2904 family is intended for general-purpose amplifier, comparator, and voltage-control applications where economy, wide supply-voltage operation, and straightforward PCB implementation are important. An operational amplifier is an analog building block that amplifies the difference between two input voltages. Within the broader semiconductor hierarchy, this product is a general-purpose operational amplifier, or op amp, used in analog signal chains, feedback-control loops, sensor interfaces, and buffer stages. The dual configuration allows one IC to implement two independent amplifier channels, reducing board area and simplifying designs that compare, amplify, filter, or condition two signals. The LM2904ATH-13 provides two independent channels with high open-loop gain and approximately 700 kHz gain-bandwidth performance. Its general-purpose positioning makes it suitable for audio preamplification, transducer conditioning, DC signal amplification, and low-to-moderate-frequency control applications. The 8-pin TSSOP package supports compact surface-mount layouts, while the tape-and-reel suffix identifies the production packing format. Exact input-offset, input-bias-current, output-swing, noise, and temperature limits must be confirmed against the manufacturer datasheet for the exact ordering code. The architecture is suited to conventional single-supply operation because the device can operate close to the positive rail while its output approaches the negative rail. Input common-mode range, output swing, slew rate, and stability conditions still determine whether a particular gain, load, and bypass-capacitor arrangement will meet the design objective. Decoupling should be placed close to the supply pins, and feedback components should be kept compact to minimize parasitic coupling and instability risk. Typical uses include low-level audio stages, current-to-voltage conversion for sensor outputs, general comparator configurations, small-signal amplification, and feedback control around slower feedback loops. The two independent channels can also be configured as comparators, buffers, amplifiers, or differential amplifier sections where their internal characteristics permit the intended operation. Applications requiring very low offset, low noise, high speed, low power, or rail-to-rail output should not assume that a general-purpose LM2904 is the optimal choice. For a robust design, begin with the manufacturer pin configuration and confirm the absolute-maximum ratings, common-mode limits, output-current capability, and recommended external-component values. Avoid using component-marking variants as substitutes without checking the exact pinout, supply range, temperature grade, and package. The TSSOP footprint also requires careful lead pitch and solder-joint inspection because its closely spaced leads are more difficult to inspect than wide-lead SOIC packages. This product page combines the LM2904ATH-13 ordering information, a pin-compatible replacement framework, and practical analog-layout guidance. It highlights the critical decisions engineers must make when reusing an existing 8-pin TSSOP footprint while preserving supply-voltage, common-mode, output-swing, temperature, and load-current requirements.

The device is packaged in an 8-SOIC package and is supplied on tape and reel. An operational amplifier, or op amp, is a high-gain analog signal-conditioning component that compares its inverting and non-inverting inputs and drives its output toward the difference between them. The LM2904 belongs to the broader hierarchy of dual operational amplifiers, analog amplifiers, integrated circuits, and general-purpose analog signal-processing devices. Its two channels share power pins but otherwise operate independently, allowing one package to provide amplification, buffering, filtering, or comparison functions. The principal benefits are a 1 MHz gain-bandwidth product, a 0.3 V/µs slew rate, and low supply-current drain of approximately 0.7 mA per amplifier. Each amplifier includes frequency compensation and is designed for operation from single or split supplies. The input common-mode range includes ground, which supports common single-supply signal-conditioning arrangements. The automotive-qualified ordering option is identified by the Q designation in the part number, although qualification documentation should be checked for the specific production configuration. The internal architecture is designed for dependable general-purpose operation with a useful combination of gain, bandwidth, input range, and supply flexibility. A typical noninverting amplifier gain of 100 has a closed-loop bandwidth of approximately 10 kHz, while a unity-gain configuration supports signal bandwidth up to the device's stated 1 MHz gain-bandwidth product. These figures make the amplifier suitable for slow sensor signals, audio-frequency circuits, feedback-control loops, and general analog conditioning rather than high-speed data acquisition. Typical applications include industrial sensor interfaces, automotive signal-conditioning modules, low-frequency active filters, audio preamplifier stages, current sensing with resistive shunts, and dual-rail buffer circuits. Two independent channels can process complementary signals or perform separate functions, reducing component count and conserving board area compared with two single amplifiers. When designing the circuit, check input and output common-mode limits at the actual supply voltage. Load output signals through appropriate biasing, use a stable reference for precision offset-sensitive measurements, and avoid operating the amplifier near supply-rail limits without confirming the input and output ranges. Place decoupling capacitors close to the power pins and keep feedback traces short to reduce oscillation and noise pickup. This page consolidates the device identity, ordering information, package details, pin assignment, engineering alternatives, and practical design guidance needed to evaluate the LM2904AVQDRG4 for a new analog circuit.

Its two-amplifier configuration makes it suitable for signal conditioning, transducer amplification, and analog control circuits using single or split supplies. An operational amplifier is an analog building block that amplifies the voltage difference between its differential input while using negative feedback to set closed-loop gain and bandwidth. The LM2904 belongs to the broader hierarchy of linear amplifiers, analog signal-chain ICs, and semiconductor components. It is internally compensated, which simplifies implementation by removing the need for an external compensation capacitor in standard closed-loop configurations. Key characteristics include low supply-current drain, low input bias and offset currents, and an input common-mode range that extends close to ground for single-supply applications. The typical supply-current consumption is 0.7 mA per amplifier. Its broad supply range and temperature rating support industrial control, automotive, instrumentation, and test-equipment designs where the amplifier must operate across changing supply and ambient conditions. The LM2904 architecture uses two independent, high-gain, frequency-compensated amplifiers in one package. Internal compensation establishes the dominant pole and makes unity-gain operation practical without external compensation components. The 700 kHz gain-bandwidth product supports moderate-frequency signal conditioning rather than high-speed data acquisition, so layout should minimize feedback-loop area and keep sensitive input nodes away from supply and output routing. Typical uses include sensor-amplifier front ends, low-frequency active filters, comparator-style threshold circuits with saturation recovery, audio preamplifier stages, and programmable control interfaces. For automotive and industrial systems, the wide operating-temperature range and wide supply tolerance are especially useful, while the low input bias current helps preserve sensor accuracy. When designing around the LM2904AVQPWR, verify the input common-mode range against the actual signal and supply levels, particularly near the positive rail. Decoupling capacitors should be placed directly across the supply pins, and unused amplifier inputs must be biased rather than left floating. Avoid relying on the device for millivolt-level precision tasks without checking offset, drift, and bias-current contributions for the complete signal chain. This page consolidates package details, verified distributor pricing evidence, drop-in alternatives, and application-oriented design guidance for engineers evaluating the LM2904AVQPWR. It also distinguishes supply-voltage, temperature, channel-count, and bandwidth trade-offs among pin-compatible LM2904-family options.

The operating temperature range extends from -40°C to +125°C, supporting industrial and automotive environments where temperature and qualification requirements exceed those of ordinary general-purpose amplifiers. The internally compensated architecture simplifies implementation of standard inverting, non-inverting, summing, and feedback amplifier circuits. A typical supply current is 500 µA per channel, while output current capability reaches 40 mA per channel. These characteristics make the device suitable for low-power analog signal conditioning where a 3 V minimum supply is required and the circuit must tolerate supply voltages up to 26 V. Typical uses include sensor interfaces, actuator drivers, motor-control feedback networks, battery-powered instrumentation, industrial control loops, and automotive signal-conditioning modules. The wide supply range allows operation from single or split supplies, although the differential voltage between the supply rails must remain within the device limits. Designers should verify output swing, input common-mode range, stability, and load capability across the complete supply and temperature range. Decoupling capacitors should be placed close to the supply pins, while feedback components and sensitive input routes should be kept away from switching nodes to reduce coupling and maintain low offset performance.

LM2904BIDR

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.

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.

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 - 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.

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

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

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.

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.

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.

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.

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.

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.
