PT2303 - PTC

PT2303 2W x 2 Class AB Audio Power Amplifier

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-te.
