Audio power amplifier IC uses multi-level Class D switching technology for high-efficiency, filterless operation. It operates from a 4 V to 26 V power-stage supply with 5 V analog and digital supplies, and it accepts digital I2S audio streams from 44.1 kHz to 192 kHz. The output stage supports 2xBTL, 4xSE, 2.1, and parallel-BTL configurations with up to 2x80 W peak output power into 4 ohms. Integrated protection covers DC, short-circuit, overload, over-temperature, and under-voltage conditions, with control and status through I2C and dedicated pins.
