RT5512B Datasheet Audio Amplifier

Manufacturer: Richtek

Overview: RT5512B Audio Amplifier with IV Sense General.

General Description

The RT5512B is a boosted class-D amplifier with V/I sensing.

A built-in DC-DC step-up converter is used to provide efficient power for class-D amplifier with multi-level class-H operation.

The digital audio interface supports I2S, left-justified, right-justified and TDM format for audio in with a data out used for chip information like voltage sense and current sense, which are able to be monitored via DATAO pin through proper register setting.
