Video ICs  
Stereo zoom microphone amplifier  
for camcorders  
BA7780KV  
The BA7780KV is a microphone amplifier developed for use in camcorders. The IC features an electronic volume cir-  
cuit for presetting the curve required for the stereo zoom function, a microphone element power supply regulator, a  
wind-noise rejection filter, a current limiting circuit for external accessory power supplies, and an input for external  
microphone input. The IC operates off a 3.3V power supply.  
Applications  
Camcorders  
Features  
1) Operates off a 3.0V to 5.25V power supply.  
2) Zoom microphone processing function on one chip.  
3) Built-in electronic volume for external setting of sen-  
sitivity and control voltage.  
4) Adjustable microphone element sensitivity.  
5) Matrix amplifier for stereo emphasis.  
6) Automatic switching circuit for external inputs, and  
built-in external monaural decision circuit.
