DESCRIPTION
The PT2303 is a power amplifier utilizing CMOS Technology specially designed for audio purpose. It
can deliver 2W × 2 power output tothe 5V power voltage. The powerconsumption 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.
