EMA1001 Overview
The EMA1001 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 watt of continuous average power with less than 1% distortion (THD+N) from a 5VDC supply. EMA1001 Key Specifications PSRR at 217Hz, VDD = 5V (Fig.
