COS4890 Overview
The COS4890 is a high quality audio power amplifier for portable electronic devices. It is capable of delivering 1.2 watt of continuous average power to an 8Ω BTL load with less than 1% distortion (THD+N) from a 5.2V power supply. It does not require output coupling capacitors or bootstrap capacitors, and therefore is ideally suited for mobile phone and other low voltage applications where minimal power consumption...
