LA7473V
Overview
The LA7473V is a microphone amplifier IC for video cameras that supports stereo audio recording and features low power
and the ability to operate from a 3V supply voltage. It achieves high audio quality by providing equalization circuits to
improve the frequency characteristics of the microphone and a left/right mixing circuit to improve the spatial presence of
the stereo image.
Features
Low power (For a 3.3V supply voltage : 18mW, for 4.75V : 28mW)
Low-voltage operation (2.7V minimum)
Low noise
Achieves high audio quality
- Provides built-in equalization circuits to improve the frequency characteristics of the microphone
- Provides a left/right mixing circuit to improve the spatial presence of the stereo image
Functions
Two microphone amplifier channels
Selector switch for internal and external microphones
High-pass filter (with bypass function)
Built-in microphone power supply
Ripple filter
External/internal microphone discrimination output
Mono/stereo discrimination output
Monolithic Linear IC
For Video Camera
