The EUA2307 is a 20-W, digital audio power amplifier with 4 half-bridged power drivers. The EUA2307 is a slave device that all clocks are provided by the external sources. One serial data input allows processing of up to two discrete audio channels and seamless integration to most digital audio processors. A bidirectional I2C interface allows reading or writing to change the internal register status.

The EUA2307 also features short-circuit and thermal protection preventing the device from being damaged during a fault condition. The EUA2307 is available in thermally efficient 48-pin TQFP package.
