30W, Stereo, High-Efficiency, Inductor-Less, I2S General-Purpose Class-D Audio Amplifier with DRC Control

The RT9120E is a high efficiency, I²S-input, stereo channel audio power amplifier delivering maximum 2x30W into 8Ω BTL speaker loads. It can deliver over 94% power efficiency at 2x20W and eliminate the need for heatsink and implement CMH mode to reduce pulse width at small signal, inductor current ripple is reduced and hence light load efficiency is improved.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 RT9120E is a 3-wired device receiving all clocks from external sources with standard I²S, Left-justified, Right-justified or TDM formats. It can support wide input sampling rate from 8kHz to 192kHz.The RT9120E features one band DRC and flexible input mixer, and power clipping.The recommended junction temperature range is -40°C to 150°C, and the ambient temperature range is -40°C to 85°C.
