DESCRIPTION

MAS6116 is a stereo volume control for audio systems, which require high output voltages (AC3).

It has serial interface, which controls two audio channels. Simple serial interface allows microcontroller to control many MAS6116 chips on the same PCB board. “Clicking” between gain changes is eliminated by changing gain only when zero crossing has been detected in the input signal.
