The device is a two-channel digital audio amplifier designed for use in automotive head
units and external amplifiers. It provides two channels at 28 W into 4 Ω at 10% THD+N from 14.4 V
or 46 W into 2 Ω at 10% THD+N. The digital PWM topology provides dramatic improvements in
efficiency over traditional linear amplifier solutions. This reduces the power dissipated by the
amplifier by a factor of ten under typical music playback conditions. The device incorporates a
patented PWM design that provides excellent power-supply rejection in the harsh electrical
environment common in automotive applications. Applications attain high efficiency without the need
for complicated power supply schemes. The design allows synchronization of multiple devices.
The device incorporates all the functionality needed to perform in the demanding OEM
applications area, including load diagnostic functions for detecting and diagnosing misconnected
outputs.
