EUA2035 - 3W/CH Stereo Filterless Class-D Audio Amplifier

Description

The EUA2035 is a high efficiency, 2 channel bridged-tied load (BTL), class-D audio power amplifier with headphone output.

Operating from a 5V power supply, EUA2035 is capable of delivering 3W/ channel of continuous output power to a 4Ω load with 10% THD+N.

Features

an advanced 64-step DC volume control which offers a range of speaker gain from -70dB to 25dB and a range of HP gain from -95dB to 3.5dB. 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 filterless architecture allows the device to drive the speaker directly, without low-pass output filters, which will save system cost and PCB area. The EUA203.
