RT9120M Datasheet | Richiek

Description The RT9120M is a high efficiency, I2S-input, stereo channel audio power amplifier delivering 2x20W into 8 BTL speaker loads. It can deliver over 92% power efficiency and eliminate the need for heat-sink. The built-in anti-pop functions can reduce the speaker’s pop noise under all kind of scenarios. Built-in protection circuits can provide over-temperature, overcurrent, overvoltage, and undervoltage protections and report error status. The RT9120M is a 3-wired device receiving all clocks from external sources with standard I2S, Left-justified, Right-justified and TDM formats. It can support both master and slave mode with wide input sampling rate from 8k Hz to 192k Hz. A fully programmable data path routes these channels to the internal speaker drivers. The RT9120M features one band DRC and flexible input mixer, and power limiting.
