EUA6204A
3W Mono Fully Differential
Audio Power Amplifier
DESCRIPTION
The EUA6204A is a mono fully-differential audio
amplifier, capable of delivering 3W of continuous
average power to an 3Ω BTL load with less than 10%
distortion (THD+N) from a 5V power supply, and
720mW to a 8Ω load from a 3.6V power supply.
The EUA6204A is ideal for PDA/notebook and portable
devices application due to features such as -80-dB
supply voltage rejection from 20Ha to 2kHz, improved
RF rectification immunity, and a fast startup with
minimal pop.
The EUA6204A is available in a SOP-8(FD).
