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.
