MAS9116 - Stereo Digital Volume Control

General Description

MAS9116 is a stereo volume control for audio systems, which require high output voltages (AC3).

It has a 16-bit serial interface, which controls two audio channels.

Simple serial interface allows microcontroller to control many MAS9116 chips on the same PCB board.

Key Features

  • Zero Detection for Gain Changes Gain Range +15.5db…-111.5dB 0.5 dB Step Size Mute Pin and Register Power On/Off Transient Suppression Signal Peak Level Comparator with Adjustable Reference.

It has a 16-bit serial interface, which controls two audio channels. Simple serial interface allows microcontroller to control many MAS9116 chips on the same PCB board. “Clicking” between gain changes is eliminated by changing gain only when zero crossing has been detected from the signal. The use of external operational amplifier provides flexibility for the operating voltage, signal swing, noise floor and cost optimization.
