BA3123F-E2

Overview

The BA3123F-E2 is a dual-channel ground isolation amplifier designed for automotive audio applications. It operates within a power supply voltage range of 4V to 18V and supports an operating temperature range from -40°C to +85°C. The device features a typical common-mode rejection ratio of 57dB at 1kHz, low noise performance with VNO of 3.5μVrms, and low distortion characterized by THD of 0.002%. It utilizes an 8-pin SOP package.

Feature Summary

Eliminates problems caused by wiring resistance in automotive environments
Removes noise generated by other electrical devices used in automobiles
Requires small external capacitor values for compact design

Applications

Car audio applications
Ground isolation amplification
Automotive noise removal circuits

Procurement Notes

Verify component status as the BA3123F-E2 is listed as End-of-Life or Last Time Buy by multiple distributors. Confirm availability through official ROHM channels or authorized partners before finalizing designs. Check for RoHS compliance documentation and ensure the specific suffix matches project requirements. Validate lead times due to potential discontinuation.

Selection Notes

Select this component for automotive audio systems requiring effective ground loop noise elimination without large external capacitors. Ensure the design accommodates the 4V to 18V supply range and -40°C to 85°C temperature limits. Consider the 8-SOP package constraints for PCB layout. Verify that the high common-mode rejection ratio meets the specific noise immunity requirements of the target application.

Part Context

The BA3123F belongs to ROHM's series of ground isolation amplifiers specifically engineered for automotive use. It addresses challenges related to wiring resistance and electromagnetic interference from other vehicle electronics. The family emphasizes compactness by minimizing external passive component requirements, facilitating reliable integration into space-constrained automotive audio setups.
