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.

FEATURES      

• Signal Voltage up to ± 18V

• Two Independent Channels

• Use of Differential DACs Possible

• Serial Control Registers

• Zero Cross Detection for Gain Changes

• Gain Range +15.5db…-111.5dB

• 0.5 dB Gain Step Size

• Mute Pin

• Power On/Off Transient Suppression

• Signal Peak Level Comparator with Adjustable Reference

• Independent Writing to Both Channels

• Instant Gain Change Function for Fast Gain Switching

• XMUTE Using the Zero Cross and Timeout Functions

• Write Operation Status Register

 APPLICATION

• High End Audio Systems

• Multi-channel Audio Systems
