Audio Accessory IC Series

Ground Isolation

Amplifier

BA3121F, BA3123F

No.09092EAT01

●Description

The BA3121F/BA3123F are ground isolation amplifiers developed for use in car audio applications.

This IC efficiently eliminate problems caused by wiring resistance, and remove noise generated by the electrical devices

used in automobiles. The capacitance values of the external capacitors required for the ICs are small to allow compact

and reliable set design.

●Features

1) Large capacitors not required

2) High common-mode rejection ratio (57dB typ. at f = 1kHz).

3) Low noise (VNO = 3.5μVrms Typ.).

4) Low distortion (THD = 0.002% Typ.).

5) Two channels.

●Applications

Car audio systems
