EUA2073-2.5W/CH Stereo Filterless Class-D Audio Amplifier with 64-Step DC Volume ControlDataSheet  

Description
The EUA2073 is a high efficiency, 2 channel bridged-tied load (BTL), class-D audio power amplifier. Operating from a 5V power supply, EUA2073 is capable of delivering 2.5W/channel of continuous output power to a 4Ω load with 10% THD+N. The EUA2073 features an advanced 64-step DC volume control which offers a range of speaker gain from -70dB to 24dB. The new filter-less architecture allows the device to drive the speaker directly, without low-pass output filters, which will save system cost and PCB area.
The EUA2073 also features short-circuit and thermal protection preventing the device from being damaged during a fault condition. The EUA2073 is available in 16-pin SOP packages.
