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.
MAS6116 also features a peak detection circuitry
that allows easy monitoring of the output signal.
MAS6116 has also a set of “instant gain change”
instructions that allow fast gain switching. The use
of external operational amplifier provides flexibility
for the operating voltage, signal swing, noise floor
and cost optimization.
Signal Voltage up to ± 18V
Two Independent Channels
Use of Differential DACs Possible
Serial Control Registers
