EMA1901 Overview
The EMA1901 is an audio power amplifier primarily designed for portable munication applications such as mobile phones and portable multimedia players (PMP). To an 8Ω BTL load, it can deliver 1.25 watt of continuous average power with less than 1% distortion (THD+N) from a 5VDC supply. Typical THD+N is about 0.015% at 1Watt.
