The RT9120S is a high efficiency, I<sup>2</sup>S-input, stereo channel audio power amplifier delivering maximum 2x30W into 8Ω BTL speaker loads. It can deliver over 94% power efficiency at 2x10W and eliminate the need for heatsink.<br /><br />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.<br /><br />The RT9120S is a 3-wired device receiving all clocks from external sources with standard I<sup>2</sup>S, Left-justified, Right-justified or TDM formats. It can support wide input sampling rate from 8kHz to 192kHz.<br /><br />The RT9120S features one band DRC and flexible input mixer, and power clipping.
