The RT9107B is a high efficiency, I2S-input, stereo or 2.1-channel audio power amplifier delivering 2x18W into 8Ω BTL speaker loads. It can deliver over 90% power efficiency and eliminate the need for heat sink.
The built-in anti-pop function can reduce the speaker's pop noise under all kind of scenarios. Built-in protections include over temperature, over current, over voltage, and under voltage protections and report error status.
The RT9107B is an I2S slave-only device receiving all clocks from external sources. It can support a wide input sampling rate from 8kHz to 96kHz, and operate with a PWM switching frequency of 352kHz or 384kHz, depending on the input sampling rate. A fully programmable data path routes these channels to the internal speaker drivers.
The RT9107B features dual-band DRC and flexible multi-band biquads for anti-clipping, power limiting, and speaker equalization. Programmable signal path routing enables Rich-surround effect and Rich-bass enhancement implementation.
