Abstract

An eight channel digital audio amplifier solution using pulse width modulation (PWM) and power stage providing superior dynamic range performance and a high level of system integration is presented. The typical dynamic range in a well-designed system is better than 110 dB and 115dB is possible in a parallel coupling setup. Including the Power Supply Volume Control (PSVC) feature additional 24 dB dynamic range is possible at normal listening levels in a typical application
