BA3121 Datasheet PDF - ROHM Semiconductor

●The BA3121,BA3121F and BA3121N are ground isolation amplifiers 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 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.
