EUA6204C
1.36-W Mono Fully Differential Audio Power AmplifierDescription
The EUA6204C 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 an 8Ω load from a 3.6V power supply.
The EUA6204C is ideal for PDA/smart phone application due to features such as -80-dB supply voltage rejection from 20Hz to 20kHz, improved RF rectification immunity, small 20mm2 PCB area, and a fast startup with minimal pop.
The EUA6204C is available in a MSOP-8 and in the space-saving 3mm × 3mm DFN package.
