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 115 dB 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.
