Overview
Description
Digitally controlled singlechannel audio attenuator fabricated on a CMOS process.
Attenuation is variable in 1 dB steps from 0 dB to 62 dB.
Mute function disconnects the input from the output, providing over 100 dB of attenuation.
Low Total Harmonic Distortion (THD) of 0.0008% and a Dynamic Range of 115 dB.
Controlled by a TTL/CMOS compatible 3wire serial digital interface.

Features
3Wire Serial Interface
Mute Function
Click and Pop Free Attenuation Changes
8Pin Plastic PDIP and SOIC Packages Available

Applications
Communication Systems
Cellular Phones and Pagers
Personal Computer Audio Control
Electronic Music (MIDI)
Sound Reinforcement Systems
Audio Mixing Automation
