EUA2306-20W Stereo Digital Audio Power Amplifier 

Description
The EUA2306 is a 20-W, efficient, digital audio power amplifier with 4 half-bridged power drivers. The EUA2306 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. The speaker protection circuitry is integrated EUA2306 to limit the amount of current through the speaker.
The EUA2306 also features short-circuit and thermal protection preventing the device from being damaged during a fault condition. The EUA2306 is available in thermally efficient 48-pin TQFP package.
