UNISONIC TECHNOLOGIES CO., LTD PA6204 Preliminary CMOS IC 1.7-W MONO FULLY DIFFERENTIAL AUDIO POWER AMPLIFIER SOP-8 DESCRIPTION The UTC PA6204 is a mono fully-differential audio amplifier, capable of delivering 1.7W of continuous average power to an 8-Ω BTL load with less than 10% distortion from a 5V power supply. The UTC PA6204 is ideal for PDA/smart phone applications due to features such as -80-dB supply voltage rejection from 20Hz to 2kHz, improved RF rectification immunity, small 20mm2 total PCB area, and a fast startup with minimal pop. The device operates from 2.5V to 5.5V, drawing only 4mA of quiescent supply current. The UTC PA6204 is suitable for diverse applications, such as PDAs, Wireless or cellular handsets, Portable devices.
