Texas Instruments  TAS6424LQDKQRQ1

The TAS6424L-Q1 device is a four-channeldigital-input Class-D audio amplifier designed for use in automotive head units and externalamplifier modules. The device provides four channels at 27 W into 4 Ω at 10% THD+N and27 W into 2 Ω at10% THD+N from a 14.4 V supply . The Class-D topology dramatically improves efficiency over traditional linearamplifier solutions. The output switching frequency can be set either above the AM band, whicheliminates the AM-band interference and reduces output filtering and cost, or below AM band tooptimize efficiency.

The wide supply-voltage range from 4.5 V to 18 V helps minimizeaudio artefacts in start-stop applications

The device incorporates all the functionality required to perform in the demanding OEMapplications area. The device has a built-in load diagnostic function for detecting and diagnosingmisconnected outputs as well as detection AC-coupled tweeters to help to reduce test time duringthe manufacturing process.

The device is offered in a 56-pin HSSOP PowerPAD™ package with the exposed thermal pad up.
