BA7780KV General Description
The BA7780KV is a microphone amplifier developed for use in camcorders. The IC features an electronic volume circuit 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.
BA7780KV Features
Operates off a 3.0V to 5.25V power supply.
Zoom microphone processing function on one chip.
Built-in electronic volume for external setting of sensitivity and control voltage.
Adjustable microphone element sensitivity.
Matrix amplifier for stereo emphasis.
Automatic switching circuit for external inputs, and built-in external monaural decision circuit.
