RT9120S 30W, Stereo, Ultra Low Noise, High-Efficiency, Inductor-Less, I2S General-Purpose Class-D Audio Amplifier with DRC Control General Description The RT9120S is a high efficiency, I2S-input, stereo channel audio power amplifier delivering maximum 2x30W into 8 BTL speaker loads. It can deliver over 94% power efficiency at 2x10W and eliminate the need for heatsink. 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, undervoltage protections and report error status. The RT9120S is a 3-wired device receiving all clocks from external sources with standard I2S, Left-justified, Right-justified or TDM formats.
