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 4 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.
FEATURES
