RT5510 Datasheet | Richtek

Description The RT5510 is a boosted BTL 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-G operation. The digital audio interface supports I2S, left-justified, right-justified, TDM and DSP A/B 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 through proper register setting.
