RT5512B

Audio Amplifier with IV Sense

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.
