RT5510

Audio Amplifier with IV Sense

General Description

Features

 Class-D Speaker AMP

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.

 4.8W Output Power @ 9.5V, 8 Load, THD < 1%

 6.5W Output Power @ 9.5V, 4 Load, THD < 1%

 0/3/6/9/12/15/18dB Boost Gain

 20V Output Noise
