Product Summary

The BA3121F-E2 is a ground isolation amplifier, which is developed for use in car audio applications. These ICs efficiently eliminate problems caused by wiring resistance, and remove noise generated by the electrical devices used in automobiles. The capacitance values of the BA3121F-E2 required for the ICs are small to allow compact and reliable set design.

Parametrics

BA3121F-E2 absolute maximum ratings: (1)power supply voltage: 18 V; (2)power dissipation: 450 mW; (3)operating temperature: -30 to +85 ℃; (4)storage temperature: -55 to +125 ℃.

Features

BA3121F-E2 features: (1)Large capacitors not required; (2)High common-mode rejection ratio (57dB typ. at f = 1kHz); (3)Low noise (VNO = 3.5mVrms Typ.); (4)Low distortion (THD = 0.002% Typ.); (5)Two channels.
