The BA3131FS contains two built-in circuits with operational amplifiers configured of three differential input circuits, an output circuit, and a switch circuit. The three differential input circuits are separate, enabling independent settings to be entered for the gain and frequency characteristics.

Applications

Car stereos, audio amplifiers and other electronic circuits

Features

1) High gain and low distortion. (Gv = 110dB, THD = 0.0015% typ.)

2) Low noise. (Vn = 2µVrms typ.)

3) Switching circuit can be directly coupled to microcomputer port.

4) Small switching noise.

5) Equipped with 1 / 2 Vcc output circuit for single power supply.
