BA82902YFJ-CE2

Overview

The BA82902YFJ-CE2 is a four-channel ground-sense operational amplifier from ROHM Semiconductor, designed for automotive applications with AEC-Q100 Grade 1 qualification. It operates on a single or dual power supply ranging from 3V to 36V. Key electrical parameters include a gain-bandwidth product of 500 kHz, a slew rate of 0.2 V/µs, and an input offset voltage of 2 mV. The device draws 700 µA of supply current per channel and provides 30 mA output current. It features low input bias current of 20 nA and high common-mode rejection ratio of 70 dB. The component is housed in a 14-SOP package and functions within a temperature range of -40°C to 125°C.

Feature Summary

• Ground-sense capability allowing input and output voltages to operate near the ground level (VEE).
• High electromagnetic interference (EMI) immunity performance suitable for noisy automotive environments.
• Wide operating supply voltage range supporting both single and dual power supply configurations.
• Automotive-grade reliability certified under AEC-Q100 standards.

Applications

• Automotive sensor signal conditioning circuits requiring ground-level sensing.
• Battery management systems in electric vehicles.
• Noise-sensitive analog signal processing in ADAS modules.
• Current sensing interfaces in automotive power distribution units.

Procurement Notes

Verify the specific suffix 'J' against the official datasheet to confirm pinout compatibility, as variations exist within the BA8290x series. Confirm that the 'NRND' status does not impact existing production runs if replacing legacy components. Ensure the SOP-J14 package dimensions match the target PCB footprint. Check RoHS compliance documentation for the specific manufacturing batch. Validate AEC-Q100 Grade 1 certification requirements against system specifications.

Selection Notes

Select this component when ground-referenced input signals are required without negative supply rails. The low bandwidth and slew rate make it suitable for DC or low-frequency applications rather than high-speed signal processing. Consider the 30 mA output drive capability for direct load interfacing. Evaluate the 700 µA quiescent current against power budget constraints. Ensure the 14-SOP package fits the available board space and thermal requirements.

Part Context

This part belongs to the BA8290xYxxx-C series of ground-sense operational amplifiers developed by ROHM Semiconductor. The series is specifically engineered for automotive electronics, emphasizing noise tolerance and reliability. The BA82902 variant integrates four independent amplifier channels in a compact surface-mount package. It shares functional similarities with other members of the family but differs in channel count and specific electrical characteristics.

Replacement Considerations

BA82902YF-CE2 is a compatible alternative with identical functionality but may differ in packaging suffixes. Verify pin-to-pin compatibility before substitution. Other series members like BA2902F offer similar ground-sense features but require verification of package and electrical parameter alignment.
