The RT9120M is a high efficiency, I<sup>2</sup>S-input, stereo channel audio power amplifier delivering 2x20W into 8Ω BTL speaker loads. It can deliver over 92% power efficiency and eliminate the need for heat-sink.<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, and undervoltage protections and report error status.<br /><br />The RT9120M is a 3-wired device receiving all clocks from external sources with standard I<sup>2</sup>S, Left-justified, Right-justified and TDM formats. It can support both master and slave mode with wide input sampling rate from 8kHz to 192kHz. A fully programmable data path routes these channels to the internal speaker drivers.<br /><br /> The RT9120M features one band DRC and flexible input mixer, and power limiting.
