EUA2035

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

64-Step DC Volume Control, AGC and Headphone Output

DESCRIPTION

FEATURES

ꢀ

Wide Supply Voltage: 2.7V to 5.5V

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 4ꢀ load with 10% THD+N. The EUA2035

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.
