The RT9121 is a high efficiency, I2S-input, stereo channel audio power amplifier delivering 2x30W into 8Ω BTL speaker loads. It can deliver over 94% power efficiency and eliminate the need for heat-sink.
Built-in protection circuits can provide over-temperature, overcurrent, overvoltage, DC and undervoltage protections and report error status.
The RT9121 is an I2S device receiving all clocks from external sources. It can support both master and slave mode with wide input sampling rate from 8kHz to 192kHz. A fully programmable data path routes these channels to the internal speaker drivers.
The RT9121 features three band DRC and flexible multi-band biquads for anti-clipping, power limiting, and speaker equalization.
