LM2902KAVQPWRQ1 - 30V Quad AEC-Q100 Op Amp | TI
MPN: LM2902KAVQPWRQ1 ✓ نشطLM2902KAVQPWRQ1 نظرة عامة
An operational amplifier is an analog signal-processing IC that amplifies the voltage difference between its inverting and non-inverting inputs. The quad operational-amplifier category combines four amplifiers in one package, while the broader hierarchy includes voltage-feedback amplifiers, analog amplifiers, and integrated circuits. This makes the LM2902KAVQPWRQ1 useful wherever several low-to-moderate-bandwidth analog channels must operate from the same supply.
Automotive qualification is a defining feature of the LM2902-Q1 family. According to the Texas Instruments LM2902-Q1 product information, the LM2902-Q1, LM2902B-Q1, and LM2902BA-Q1 devices are qualified in accordance with AEC-Q100 specifications. Other key characteristics include 2 kV improved ESD capability, a 0.5 V/µs slew rate, and an input common-mode voltage range that includes ground. The latter supports practical single-supply designs when the signal remains near the lower supply rail.
The KAV version combines the standard bipolar amplifier architecture with 1.2 MHz gain-bandwidth performance and 2 mV offset voltage. Its four amplifier sections share the positive and negative supply pins, while each section retains its own input and output terminals. A gain-bandwidth product near 1.2 MHz supports general-purpose closed-loop operation well below the amplifier's upper frequency limit, depending on feedback topology and acceptable phase margin.
Typical uses include automotive sensor interfaces, low-frequency active filters, transimpedance amplifiers, audio signal conditioning, battery monitoring, actuator drivers, and general analog control loops. The 14-pin TSSOP package reduces board footprint relative to four separate single or dual amplifier packages. Tape-and-reel packaging supports automated assembly, while the automotive qualification supports designs subject to rigorous reliability requirements.
When designing around the LM2902KAVQPWRQ1, verify the complete input and output voltage limits under temperature and load conditions. Keep sensitive input traces away from switching nodes and provide local supply bypassing near the package. Account for output swing, slew-rate limits, input common-mode range, and stable feedback components when selecting gain and compensation values.

LM2902KAVQPWRQ1 مناسب لـ 6 التطبيقs: Automotive Sensor Signal Conditioning, Battery Monitoring and Control, Low-Frequency Active Filtering, Audio and Communications Buffering, Actuator and Driver Interface Circuits, Industrial Control and Instrumentation.
Automotive Sensor Signal Conditioning
The LM2902KAVQPWRQ1 suits automotive sensor interfaces requiring four amplifier channels, AEC-Q100 qualification, and operation from a 3 V to 32 V supply. Its 1.2 MHz gain-bandwidth product is ample for many wheel, pressure, position, and body-system sensors operating at low or moderate frequencies, while 2 mV input offset limits signal error near the sensing floor. The input common-mode range includes ground, helping simplify single-supply interface designs. Four amplifiers can handle buffering, level conditioning, active filtering, and output drive within one 14-pin TSSOP, reducing board area compared with separate amplifier packages.

Battery Monitoring and Control
The LM2902KAVQPWRQ1 can monitor multiple battery-related voltages in automotive and industrial power systems because four independent amplifiers share a 3 V to 32 V supply. Individual channels may buffer sensed cell or rail voltages, amplify small current-shunt signals, and provide gain to an analog-to-converter input. The 2 mV offset specification is particularly relevant to low-level shunt measurements, while the 0.5 V/µs slew rate supports moderate-amplitude control signals. Its AEC-Q100 qualification makes the device appropriate for qualified vehicle power systems where component robustness and availability across grade options are required.
موصى به
Low-Frequency Active Filtering
The LM2902KAVQPWRQ1 is well suited to first- and second-order active filters built around its four 1.2 MHz bipolar amplifier channels. A wide-gain-bandwidth ratio provides useful bandwidth beyond the intended low-frequency passband, allowing conventional RC compensation networks to shape sensor or communications signals. Four channels can implement a complete signal chain without using four packages, and the 2 mV offset value helps control DC error in precision-oriented filters. The design must remain within the output swing and input common-mode limits, which include ground but do not extend to the positive supply rail.

Audio and Communications Buffering
The LM2902KAVQPWRQ1 can provide impedance buffering and gain for low-frequency audio, communications, or instrumentation signals. Its 1.2 MHz gain-bandwidth product comfortably supports many audio-band tasks, and the 0.5 V/µs slew rate helps reproduce medium-amplitude waveforms without excessive distortion. The four-channel arrangement is useful for input stages, differential summing functions, filters, and output drivers within one compact TSSOP. Designers should account for the bipolar amplifier’s output-swing limits, noise characteristics, and stability when driving capacitive loads, while single-supply designs should keep inputs within the common-mode range that includes ground.

Actuator and Driver Interface Circuits
The LM2902KAVQPWRQ1 can serve as the analog interface between sensors, logic, and automotive actuators where four medium-speed channels are needed. A typical arrangement uses separate amplifier sections for command conditioning, feedback sensing, offset correction, and output driving. The 0.5 V/µs slew rate supports moderate-frequency transitions, and the 3 V to 32 V operating range accommodates vehicle electrical environments. Because this is a linear amplifier rather than a power-output stage, the external transistor or driver must provide the required load current; the LM2902KAVQPWRQ1 supplies control, gain, and isolation within the system.
موصى به
Industrial Control and Instrumentation
The LM2902KAVQPWRQ1 is useful in compact control boards requiring several general-purpose analog channels under a wide supply range. Four sections can amplify pressure, position, temperature, and feedback signals while operating from the same 3 V to 32 V rail. The 1.2 MHz gain-bandwidth product and 2 mV offset rating provide useful performance for slow closed-loop measurements, and the common-mode input range includes ground for single-supply sensors. Its TSSOP-14 package simplifies compact, high-density layouts, although industrial system qualification requirements beyond AEC-Q100 should be assessed independently for the selected ordering code.

ملاحظات التصميم
Confirm that input and output voltages remain inside the amplifier limits at every supply level and temperature. The input common-mode range includes ground, which supports single-supply operation, but the positive end of that range is not the positive supply rail. Use the manufacturer datasheet limits when designing bias points for 3 V, 5 V, 12 V, or vehicle-level supplies, and include adequate supply bypassing at pins 4 and 11.
Place the input, output, feedback, and compensation components close to their associated TSSOP pins. Keep amplifier A pins 2 and 3 away from pins 4 and 11, power inductors, switching nodes, and high-current return paths. Because all four sections share the same supply pins, a common supply disturbance can affect every channel. Use a short ground return and a local bypass capacitor near the package rather than routing sensitive inputs through a shared ground path.
Check closed-loop bandwidth against the 1.2 MHz gain-bandwidth product and verify stability with the selected feedback and compensation network. The 0.5 V/µs slew rate limits large-signal performance: estimated rise time for a full 10 V step is 20 µs using 0.5 V/µs. Ensure the desired output amplitude and frequency remain within that limit, and avoid driving a capacitive load directly unless the application note or manufacturer guidance confirms stability.
