2.5W × 2 Class AB Audio Power Amplifier
PT2305
DESCRIPTION
The PT2305 is an audio power amplifier utilizing CMOS Technology specially designed for audio
purpose. It can deliver 2.5W × 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 structure is BTL (Bridge-Tied Load)
mode for driving speaker load mode. Built-in over-temperature protection, package size is not occupies
PCB space. It is suitable for small or portable products.
FEATURES
