9.1 Overview

The TAS6424E-Q1 is a four-channel digital-input Class-D audio amplifier specifically tailored for use in the

automotive industry. The device is designed for vehicle battery operation or boosted voltage systems. This

ultra-efficient Class-D technology allows for reduced power consumption, reduced PCB area, and reduced heat.

The device realizes an audio sound-system design with smaller size and lower weight than traditional Class-AB

solutions.

The core design blocks are as follows:

• Serial audio port

• Clock management

• High-pass filter and volume control

• Pulse width modulator (PWM) with output stage feedback

• Gate drive

• Power FETs

• Diagnostics

• Protection

• Power supply

• I2C serial communication bus
