Conference Paper

A Single-Chip Solution for Stereo Volume Control

Authors: Green, Steven R.; Harris, Larry L.

AES Conference: 13th International Conference: Computer-Controlled Sound Systems · Paper 13-030 · December 1994

Abstract

A CMOS stereo volume control has been designed specifically for digital control of analog audio signals. It features a 3-wire interface that controls two independent audio channels with 95.5 dB of attenuation and 31.5 dB of gain with 0.5-dB resolution. Zipper noise has been virtually eliminated with the implementation of zero-crossing detection. The part achieves a 0.0007% THD over a 20-Hz to 20-kHz bandwidth.
