BA82902YFVJ-CE2

Overview

The BA82902YFVJ-CE2 is a four-channel automotive-grade ground-sense operational amplifier manufactured by ROHM Semiconductor. It operates within a supply voltage range of 3 V to 36 V and supports dual supplies from 1.5 V to 18 V. Key electrical parameters include a gain-bandwidth product of 500 kHz, a slew rate of 200 mV/µs, and an input offset voltage of 2 mV. The device draws 700 µA of operating current per channel and provides a typical output current of 30 mA. It features a common-mode rejection ratio of 70 dB and is qualified under AEC-Q100 standards for Grade 1 reliability.

Feature Summary

• Ground-sense capability allowing direct sensing at the ground level with input voltage ranges extending to VEE.
• Automotive qualification compliant with AEC-Q100 Grade 1 standards for high reliability in vehicle environments.
• Wide single or dual power supply operation supporting voltages from 3 V up to 36 V.

Applications

• Automotive sensor signal conditioning circuits
• Current sensing applications requiring ground-level reference
• Battery management systems in electric vehicles

Procurement Notes

Verify component authenticity through authorized distributors as the part status is Not Recommended for New Designs (NRND). Confirm package integrity upon receipt, as the TSSOP-B14J form factor requires careful handling during surface mount assembly. Ensure compliance with RoHS directives and check for moisture sensitivity level ratings before storage and reflow soldering processes.

Selection Notes

Select this component when designing automotive circuits that require ground-referenced inputs without negative supply rails. The four-channel configuration offers space efficiency compared to discrete solutions. Consider the 500 kHz bandwidth and low bias current for precision analog signal processing tasks where power consumption must remain minimal under wide supply voltage variations.

Part Context

This device belongs to the BA8290xYxxx series of ground-sense operational amplifiers designed specifically for automotive electronics. The series emphasizes low power consumption and robust performance across the extended industrial temperature range of -40°C to +125°C. It serves as a specialized solution for applications demanding high common-mode rejection and direct ground interfacing capabilities.
