The TAS6424E-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.

The devices adds EMI management features including spread-spectrum, output phase offset and optimized slew rate to assist in system level EMI challenges.

The TAS6424E-Q1 Class-D audio amplifier is designed for use in automotive head units and external amplifier modules. For pin compatible one, two and four-channel devices see the the Device Options table.
