LM2904VQPWRQ1 - 26V Dual 700kHz Op Amp | Texas Instruments
MPN: LM2904VQPWRQ1 ✓ Hoạt độngLM2904VQPWRQ1 Tóm tắt
An operational amplifier is a high-gain, high-impedance analog signal-processing component that compares its differential input voltage with a feedback network to produce an amplified output. The dual-amplifier configuration places two amplifiers in one package, reducing board area in applications such as sensor conditioning, current-loop signal processing, filtering, and general-purpose analog amplification. LM2904-Q1 belongs to the operational-amplifier, amplifier IC, and analog IC hierarchy within semiconductor signal-conditioning electronics.
The LM2904VQPWRQ1's key attributes are its dual-circuit architecture, 26 V maximum total supply rating, 700 kHz gain-bandwidth product, and ability to operate across a 3 V to 32 V supply range. AEC-Q100 qualification supports its use in automotive electronic systems, while the extended -40°C to +125°C ambient-temperature range addresses industrial temperature requirements. Low supply current and ESD protection are additional features identified in the family datasheet.
The amplifier family is designed for general-purpose operation rather than high-speed precision signal paths. Its 700 kHz bandwidth is suitable for moderate-frequency conditioning, while the automotive qualification and wide supply operating range suit electronic control units, sensor interfaces, actuator drivers, battery-powered systems, and industrial measurement modules. Users should confirm output-swing, input-common-mode, offset, and stability limits against the specific operating conditions in the manufacturer datasheet before finalizing a design.
Typical applications include low-side current sensing in automotive electronic control units, conditioning resistive sensor signals, amplifying sensor and transducer outputs, active filtering, and general voltage amplification. The two amplifier sections can process related signal paths while sharing one supply package, which simplifies power distribution and reduces component count compared with two discrete single amplifiers.
PCB design should provide a stable ground reference, short feedback paths, appropriate input-biasing, and decoupling close to the supply pins. Because automotive environments can contain electrical transients and ESD events, system-level protection and validation remain essential even though the amplifier family includes ESD-protection features. Confirm pin orientation and signal names against the manufacturer pin-configuration table before layout release.
This page organizes the automotive dual operational amplifier's electrical limits, package information, design considerations, application guidance, and verified drop-in alternatives. It also distinguishes exact ordering variants by their documented package and qualification differences, helping engineers identify a replacement that fits the same TSSOP footprint before conducting board-level and system validation.

Ứng dụng tiêu biểu
LM2904VQPWRQ1 phù hợp cho 6 Áp dụngs: Automotive Sensor Signal Conditioning, Low-Side Current Sensing, Active Filter and Control Loops, Battery and Automotive Power Monitoring, Industrial Transducer Interfaces, General-Purpose Voltage Amplification.
Automotive Sensor Signal Conditioning
LM2904VQPWRQ1 fits automotive sensor conditioning because it combines two general-purpose amplifiers, a 700 kHz gain-bandwidth product, and operation from 3 V to 32 V in an 8-pin TSSOP package. Its AEC-Q100 qualification and -40°C to +125°C ambient range support vehicle electronics that must process moderate-bandwidth sensor signals. The two amplifier sections can amplify or buffer complementary channels without requiring two separate packages. Design the feedback network around the target gain, keep the input common-mode voltage within the manufacturer limits, and verify offset and noise requirements against the sensor signal level. Decoupling and grounding remain critical because automotive environments combine low-frequency utility signals with transient and ESD events.

Low-Side Current Sensing
LM2904VQPWRQ1 is appropriate for amplifying the small differential voltage produced by a low-side current-sense shunt. Its 700 kHz gain-bandwidth product provides useful bandwidth for many automotive and industrial current-control loops, while the dual configuration can condition a shunt signal and support an additional voltage or current function. The amplifier operates from 3 V to 32 V, allowing it to work with low-voltage sensor rails and higher-voltage automotive systems. Keep the shunt differential pair routed away from switching nodes, use a balanced return path, and select shunt and feedback resistors to avoid clipping. Validate common-mode limits, input offset, and output swing at minimum and maximum measured current.

Active Filter and Control Loops
LM2904VQPWRQ1 can implement active filters and moderate-bandwidth control loops when each section is assigned to a gain or compensation function. Its 700 kHz gain-bandwidth product is the principal selection criterion for loop-bandwidth planning, while the 3 V to 32 V supply range supports varied automotive and industrial rail conditions. Two amplifiers in one TSSOP package can simplify a low-pass or feedback network and reduce package count. Place the feedback components close to the relevant output and input pins, keep the ground return continuous, and bypass the supply rail near the device. Confirm loop stability and output swing using the manufacturer recommended operating conditions before finalizing component values.

Battery and Automotive Power Monitoring
LM2904VQPWRQ1 is suitable for amplifying battery or power-rail monitoring signals in automotive electronic systems because it supports a 3 V to 32 V operating supply range and an extended -40°C to +125°C ambient range. One amplifier can monitor a divided voltage while the second handles an associated current or temperature channel, conserving board area. AEC-Q100 qualification is valuable for vehicle programs, but the input network must keep each measured node within the common-mode limits of the selected amplifier. Use resistor dividers with suitable power ratings, provide a low-impedance reference, and verify accuracy against offset and bias-current requirements. Final validation should include transient immunity and worst-case behavior across the vehicle operating range.

Industrial Transducer Interfaces
LM2904VQPWRQ1 can serve as the front-end amplifier for resistive, strain, pressure, or other transducer interfaces that require moderate bandwidth rather than precision or high-speed performance. The 700 kHz gain-bandwidth product supports practical sensor amplification, and the dual-circuit package allows two channels or a gain-plus-buffer arrangement. Its 26 V maximum total supply rating and 3 V to 32 V operating range make it useful for industrial control equipment with varied rail conditions. Select the gain to preserve usable output swing, apply input bias compensation when source resistance is high, and isolate the sensitive input from switching converters and motor nodes. Validate noise, offset, common-mode range, and stability at production temperature limits.

General-Purpose Voltage Amplification
LM2904VQPWRQ1 is a practical choice for general voltage amplification, buffering, and gain-stage implementations where two independent amplifier sections are useful in one 8-pin TSSOP package. Its 700 kHz gain-bandwidth product supports low-to-moderate signal frequencies, and the wide operating supply range provides flexibility across automotive and industrial systems. Designers can use one channel for the primary gain stage and the other for buffering, offsetting, or an additional channel. Keep the feedback network short, use a stable reference for non-inverting configurations, and confirm that the output remains within its swing limits at the required load. For precision or high-speed instrumentation, compare the offset, noise, slew-rate, and stability requirements before approving this general-purpose amplifier.

Ghi chú thiết kế
Route each differential input as a compact pair directly to the amplifier pins, and place feedback components close to the relevant output and inverting-input pins. Keep the input network away from inductors, switching nodes, and high-current return paths. A solid ground plane and short ground returns reduce common-mode pickup and help preserve the useful performance of this 700 kHz general-purpose dual amplifier.
Place the supply bypass capacitor immediately beside the positive and ground pins, with the ground termination close to the device. Follow the manufacturer recommendations for capacitance, voltage rating, and dielectric type. Because the device supports a wide supply range, verify that the selected rail remains within both the operating range and the 26 V maximum total supply rating during startup, load transients, and fault conditions.
Do not assume that the family headline bandwidth covers every gain, load, capacitance, or temperature combination. Check input common-mode range, output swing, stability, offset, noise, and slew rate in the manufacturer datasheet for the intended configuration. In automotive systems, validate ESD, transient immunity, temperature behavior, and fault operation at the system level rather than relying only on the device qualification status.
When substituting another ordering code, compare the exact PW package, pin configuration, temperature range, qualification configuration, and lifecycle status. Ordering suffixes within a family can encode more than package information. Verify the manufacturer ordering table and complete the approved change-control process before treating LM2904QPWRQ1 or a G4 variant as a production replacement.
