Texas Instruments TAS6422QDKQQ1

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 applications

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.

For a pin compatible four-channel devices see the TAS6424-Q1 device.
