Introduction
RT9120S is a high-efficiency, I2S-input, stereo-channel audio power amplifier capable of delivering up to 2×30W into 8Ω BTL speaker loads. At 2×10W output, power efficiency exceeds 94%, eliminating the need for a heatsink. The built-in anti-pop function reduces pop noise from speakers across various scenarios. Integrated protection circuits provide over-temperature, over-current, over-voltage, and under-voltage protection with error status reporting. The RT9120S is a three-wire device that accepts all clocks from an external source, supporting standard I2S, left-justified, right-justified, or TDM formats. It supports a wide input sample rate range from 8kHz to 192kHz. The RT9120S features single-band dynamic range control, a flexible input mixer, and power clipping functionality.
Features
