PT2303

DESCRIPTION

The PT2303 is a power amplifier utilizing CMOS Technology specially designed for audio purpose. It

can deliver 2W × 2 power output to the 5V power voltage. The power consumption is very low in

stand-by. Total harmonic distortion is lower than 0.03%. The output mode can be switched between

the SE (Single-Ended) or BTL (Bridge-Tied Load) mode. Built-in over-temperature protection, package

size is not occupies PCB space. It is suitable for small or portable products.
