Datasheet Summary
Advanced Stereo Headphone Amplifier
DESCRIPTION
EUA6211 is a dual audio power amplifier designed for portable munication device applications such as mobile phones. EUA6211 operates from a single 2.5V to 5.5V supply, consumes only 3.8mA of supply current, capable of delivering 30mW of continuous average power into a 16Ω load from a 3V power supply with a THD+N of 1%. Base on the power supply delivered to the device, an internal power management block generates a negative voltage. Thus, the internal amplifiers provide outputs referenced to Ground. In this configuration, the two external heavy coupling capacitors can be removed. It offers significant space and cost savings pared...
