What are the key features of LM2902KAVQPWRG4Q1?
- AEC-Q100 Grade 1 qualified for -40°C to 125°C automotive ambient temperature, ensuring reliable operation in under-hood and body-control applications
- Quad op-amp in a 14-pin TSSOP integrates 4 amplifiers to implement signal conditioning, filtering, and summing in a single compact package
- Wide ±16 V / 32 V supply range and 80 dB CMRR support precision sensor amplification on noisy automotive 12 V and 24 V power rails
What is LM2902KAVQPWRG4Q1 used for?
LM2902KAVQPWRG4Q1 is used in automotive body-control modules, battery management systems, and in-vehicle sensor signal conditioning where 4 op-amp channels are needed in a small footprint that meets AEC-Q100 reliability requirements. It amplifies resistive bridge sensors, current-sense voltages, and analog transducer outputs on 12 V automotive rails while rejecting common-mode noise. The device is also suited for HVAC control, seat position detection, and powertrain sensor interfaces in passenger and commercial vehicles.

Frequently Asked Questions
What automotive qualification level does LM2902KAVQPWRG4Q1 carry, and what does that mean for under-hood deployment?
LM2902KAVQPWRG4Q1 is AEC-Q100 Grade 1 qualified, meaning it has passed accelerated life testing for operation from -40°C to 125°C ambient temperature. Grade 1 is the standard qualification level required for under-hood automotive applications such as engine management, exhaust sensors, and power electronics modules. Using a Grade 1 part ensures the op-amp meets automotive OEM reliability requirements and reduces the risk of premature field failure due to thermal stress over the vehicle's 15-year to 20-year design lifetime.
How does the 80 dB CMRR of LM2902KAVQPWRG4Q1 benefit sensor amplification on a noisy automotive 12 V rail?
An 80 dB CMRR means the amplifier rejects common-mode noise by a factor of 10,000, so a 1 V transient on the power rail produces only 0.1 mV of output error. In a 12 V automotive system, ground-bounce and alternator ripple can reach several hundred millivolts of common-mode noise. With 80 dB CMRR at low frequencies, LM2902KAVQPWRG4Q1 amplifies only the differential sensor signal while suppressing this noise, achieving accurate readings from resistive bridge sensors, thermistors, and current-sense shunts without external filtering.
Is LM2902KAVQPWRG4Q1 suitable for a single-supply 5 V ECU design running next to a 12 V battery line?
Yes. LM2902KAVQPWRG4Q1 operates from a single supply as low as 3 V up to 32 V and includes input common-mode voltage range that extends down to the negative supply rail (ground in single-supply configurations). This allows the amplifier to process signals that swing to 0 V without requiring a split supply. In a 5 V ECU powered by an onboard LDO from the 12 V battery, the quad op-amp can handle 0 V to 5 V sensor outputs directly, and its 7 mV maximum offset voltage ensures adequate accuracy for 10-bit to 12-bit ADC input conditioning.
