DESCRIPTION

The MS6720 is a 3 stereo inputs/4-channel outputs digital control audio processor for the low voltage operation.

Volume, balance (left/right), and fader (front/rear) processor are incorporated into a single chip. The MS6720 also has

selectable input gain. All functions are programmable via the serial I²C bus. The default states of the chip as the power

is on are: the volume is -78.75dB, the stereo 4 is selected, all the speakers are mute and the gains of the input stage are

0dB. The stereo 4 is connected internally, but not available on pins.
