EUA2839-20W Stereo Digital Audio Power Amplifier with EQ, 3-Band AGL, 3D and Capless HP/Line Driver

EUA2839-20W Stereo Digital Audio Power Amplifier with EQ, 3-Band AGL, 3D and Capless HP/Line Driver 

Description
The EUA2839 is a 20-W, digital audio power amplifier with 4 half-bridged power drivers. The EUA2839 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 EUA2839 has integrated an advanced headphone amplifier and line driver to increase system-level integration and reduce total solution costs. Advanced EMI Suppression Technology enables the use of inexpensive ferrite bead filters at the outputs while meeting EMC requirements for system cost reduction.
The EUA2839 also features short-circuit and thermal protection preventing the device from being damaged during a fault condition. The EUA2839 is available in thermally efficient 48-pin LQFP package.
