EUA6204A
3W Mono Fully DifferentialDescription
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).
