December, 2005

2W x 2 Class AB Audio Power Amplifier

PT2300

DESCRIPTION

The PT2300 is a power amplifier utilizing CMOS Technology specially designed for audio purpose. It

can deliver 2W × 2 power output to the 4Ω load. 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. The built-in volume controller can change the output

volume by an external supplied DC voltage. Built-in over-temperature protection, package size is not

occupies PCB space. It is suitable for small or portable products.
