Video ICs  
Stereo microphone amplifier for cam-  
corders  
BA7781K  
The BA7781K allows construction of a stereo-microphone amplifier for camcorder use with a minimum number of  
external components. The IC has a built-in wind-noise detection circuit, and wind-noise rejection filter. The filter cir-  
cuit is controlled automatically. The IC can operate off a 3.0V power supply.  
Applications  
Camcorders  
Features  
1) Operates off a 3.0V to 5.25V power supply.  
2) Automatic wind-noise rejection circuit.  
3) Matrix circuit for stereo emphasis.  
4) Automatic switching circuit for external micro-  
phones, built-in external monaural decision circuit,  
and input switch mode decision circuit.
