The TAS6422-Q1 device is a Two-channel
digital-input Class-D audio amplifier designed for use in automotive head units and external
amplifier modules. The device provides two channels at 27 W into 4 Ω at 10% THD+N and
45 W into 2 Ω at
10% THD+N from a 14.4 V supply and 75 W into 4 Ω at 10%
THD+N from a 25 V supply. The Class-D topology dramatically improves efficiency over
traditional linear amplifier solutions. The output switching frequency can be set either above the
AM band, which eliminates the AM-band interference and reduces output filtering and cost, or below
AM band to optimize efficiency.
The wide supply-voltage range from 4.5 V to 26.4
V helps minimize audio artefacts in start-stop
The device incorporates all the functionality required to perform in the demanding OEM
applications area. The device has a built-in load diagnostic function for detecting and diagnosing
misconnected outputs as well as detection AC-coupled tweeters to help to reduce test time during
the manufacturing process.
The device is offered in a 56-pin HSSOP PowerPAD™ package with the exposed thermal pad up.
