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.
!
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 = 2
μ
Vrms 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.
