BA3131FS Standard ICs Dual operational amplifier with switch, for audio use (3 inputs × 1 output × 2) BA3131FS 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.
