Description

General part information

TAS6424 Series

The TAS6424M-Q1 device is a four-channel digital-input Class-D audio amplifier that implements a 2.1 MHz PWM switching frequency enabling a cost-optimized solution in a very small PCB size, full operation down to 4.5 V for start/stop events, and exceptional sound quality with up to 40 kHz audio bandwidth.

The output switching frequency can be set either above the AM band, which eliminates AM-band interferences and reduces output filtering and cost, or below the AM band to optimize efficiency.

The device has a built-in load diagnostic function for detecting and diagnosing misconnected outputs as well as detection of AC-coupled tweeters to help to reduce test time during the manufacturing process.
