PT2255A

PT2255A is an electronic volume controller IC utilizing CMOS Technology

specially designed for use on audio equipment. It has two (2) built-in channels

making it ideally suitable for mono and stereo sound applications. PT2255A

provides a wide frequency response range and a very low harmonic distortion to

mention a few; thereby guaranteeing a highly effective and reliable performance.
