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.  
!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.
