LM2902AQS14-13

Overview

The LM2902AQS14-13 is an automotive-compliant quad operational amplifier manufactured by Diodes Incorporated. It features a wide single supply voltage range of 3V to 36V and dual supplies from ±1.5V to ±18V. The device provides a unity-gain bandwidth of 700kHz, a large DC voltage gain of 100dB, and low input bias current of 20nA. The 'A' suffix indicates a typical input offset voltage of 1mV. Qualified to AEC-Q100 Grade 1, it operates over a temperature range of -40°C to +125°C in a TSSOP-14 package.

Feature Summary

• Automotive compliant with AEC-Q100 Grade 1 qualification and PPAP capability for specific change control requirements.
• Low power supply current drain that remains independent of the magnitude of the power supply voltage.
• Input common-mode voltage range includes ground, allowing direct detection near zero volts.
• Internally compensated for unity-gain stability with differential input voltage range equal to the power supply voltage.

Applications

• Automotive electronic systems requiring high reliability and specific change control protocols.
• Industrial control systems operating under wide voltage and temperature variations.
• Sensor signal conditioning circuits utilizing true-differential inputs at ground potential.
• General-purpose amplification in battery-powered or single-supply applications.

Procurement Notes

Verify the component matches the exact automotive grade (Grade 1) and low offset voltage variant ('A' suffix). Confirm the package code corresponds to SO-14 as indicated by the ordering information. Ensure compliance with RoHS 3 and halogen-free standards required for the specific manufacturing facility. Validate that the supplier provides necessary quality documentation supporting AEC-Q100 qualification.

Selection Notes

Select this component when automotive reliability and strict change control are mandatory. The 'A' version is appropriate for applications requiring minimal input offset voltage drift. Consider the 700kHz bandwidth and 100dB gain for general signal processing tasks. Verify that the single-supply operation down to 3V meets the system's minimum voltage requirements.

Part Context

This part belongs to the LM2902Q/LM2902AQ series of automotive-compliant operational amplifiers. It is distinct from non-automotive variants by its AEC-Q100 qualification and IATF16949 certified manufacturing. The quad configuration integrates four independent high-gain amplifiers on a single die, offering a compact solution for multi-channel signal processing in constrained spaces.
