Authors: Harris, Larry; Scott III, Baker P.

AES Convention 95 · Paper 3759 · October 1993

Abstract

A CMOS stereo volume control has been designed specifically for microprocessor-controlled audio systems. It features a 16-bit serial interface that controls two independent audio channels with a total adjustable range of 127 dB in steps of 0.5 dB. The range is divided into 95.5 dB of attenuation and 31.5 dB of gain. The part is capable of driving a load of 600 ohms in parallel with a 100-pF capacitor and achieves 0.0007% THD over a 20-Hz to 20-kHz bandwidth.
