EUA2075B-2.5W/CH Stereo Filterless Class-D Audio Amplifier with 64-Step DC Volume Control 

Description
The EUA2075B is a high efficiency, 2 channel bridged-tied load (BTL), class-D audio power amplifier. Operating from a 5V power supply, EUA2075B is capable of delivering 2.5W/channel of continuous output power to a 4Ω load with 10% THD+N. The EUA2075B features an advanced 64-step DC volume control which offers a range of speaker gain from -70dB to 20dB. The AGC detects output signal clip due to the over level input signal and suppresses it automatically. Moreover the AGC can adapt the output clip caused by power supply voltage down with battery. 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 EUA2075B also features short-circuit and thermal protection preventing the device from being damaged during a fault condition. The EUA2075B is available in 16-pin SOP package.
