RT9120M 2x20W, Inductor-Less I2S-input, Low Noise, High-Efficiency Closed-Loop General-Purpose Class-D Digital Audio Amplifier with DRC Control General 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.
