RT5508

Speaker Amplifier with Speaker Protection

Features

 Class-D Speaker AMP

General Description

The RT5508 is a mono BTL class-D amplifier with

cutting-edge speaker protection algorithm. Also, a

built-in DC-DC step-up converter is used to provide

efficient power for class-D amplifier. I²S interface

supports two different audio sources while a pair of

auxiliary DATAI/O is used for stereo mode or

pass-through application. Chip information including

gain, speaker protection output or current sense is able

to be monitored via DATAO through proper register

setting. Speaker protection provides mechanical /

thermal protection with accuracy of 10%/±10C of rated

limit.

 1.6W Output Power @ 5.3V, 8 Load, THD < 1%

 0/3/6/9/12/15dB Boost Gain

 20V Output Noise @ 0dB Gain
