BA2902YF-MGE2

Overview

The BA2902YF-MGE2 is a four-channel automotive ground-sense operational amplifier manufactured by ROHM Semiconductor. It operates within a supply voltage range of 3V to 36V and supports dual supplies from ±1.5V to ±18V. The device features a gain-bandwidth product of 500 kHz, a slew rate of 200 mV/µs, and an input offset voltage of 2 mV. It draws 700 µA of operating current and provides 30 mA output current per channel with a common-mode rejection ratio of 70 dB. Qualified under AEC-Q100 standards, it functions reliably between -40°C and +125°C in a 14-SOP package.

Feature Summary

Supports ground-sense operation allowing signal processing near the negative rail
Automotive-grade qualification ensuring reliability in harsh environments
Low power consumption suitable for battery-operated systems

Applications

Automotive sensor interface circuits
Battery monitoring systems
Ground-referenced signal conditioning

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm package integrity and storage conditions prior to assembly. Cross-reference datasheet revisions for parameter consistency. Ensure design-in compliance with functional safety requirements if applicable. Validate pinout compatibility during replacement planning.

Selection Notes

Consider the four-channel configuration for multi-sensor applications requiring ground-sense capability. Evaluate the 3V minimum supply constraint against system power rails. Assess thermal performance within the specified temperature range. Verify output drive requirements against the 30 mA limit. Review AEC-Q100 qualification for automotive deployment suitability.

Part Context

This component belongs to the BA290x series of ground-sense operational amplifiers designed for automotive use. It complements other variants like the BA2901 and BA2903 comparators within the same family. The SOP-14 package offers surface-mount convenience for compact PCB layouts. Its functionality targets applications requiring precise low-side signal detection.
