RT9125 30W Stereo, Inductor-Less Digital Audio, Closed-Loop System with 96kHz Extended Audio Processing 1 General Description The RT9125 is a high efficiency, I2S-input, stereo channel audio power amplifier delivering 2x30W into 8 BTL speaker loads. It can deliver over 94% power efficiency and eliminate the need for heat-sink. Built-in protection circuits can provide overtemperature, overcurrent, overvoltage, DC and undervoltage protections and report error status. The RT9125 is an I2S device receiving all clocks from external sources. A fully programmable data path routes these channels to the internal speaker drivers. The RT9125 features three band DRC and flexible multi-band biquads for anti-clipping, power limiting, and speaker equalization.
