STA323WQS Datasheet - STMicroelectronics

 Description
The STA323WQS is a single-chip audio system comprising digital audio processing, digital amplifier control, a DDX® power-output stage and QSound QHD®. The STA323WQS uses all-digital amplification to provide high-power, high-quality and high-efficiency.

The STA323WQS power section consists of four independent half-bridges. These can be configured, by digital control, to operate in the following modes.

Two channels, provided by two half-bridges, and a single full-bridge giving up to 2 x 10 W + 1 x 20 W of power output.
Two channels, provided by two full-bridges, giving up to 2 x 20 W of power.
A single, parallel, full-bridge channel capable of high-current operation and giving 1 x 40W output.
