1.36W單聲道 全差動架構的音頻放大器


The EUA6204 is a mono fully-differential audio amplifier, capable of delivering 1.36W of continuous average power to an 8Ω BTL load with less than 1% distortion (THD+N) from a 5V power supply, and 720mW to a 8Ω load from a 3.6V power supply.

The EUA6204 is ideal for PDA/smart phone application due to features such as -80-dB supply voltage rejection from 20Ha to 2kHz, improved RF rectification immunity, small 20mm2 PCB area, and a fast startup with minimal pop.

The EUA6204 is available in a MSOP-8 and in the space-saving 3mm × 3mm DFN package.
