PT2256V

DESCRIPTION

PT2256V is an electronic volume controller IC utilizing CMOS Technology specially designed for use

on audio equipment. It has 2 built-in channels making it ideally suitable for mono and stereo sound

applications. PT2256V provides the Loudness Function, a wide frequency response range and a very

low total harmonic distortion, thereby guaranteeing a highly effective and reliable performance. It is

housed in 16-pin DIP or SOP and is functionally compatible with TC9235P. Pin assignments and

application circuit are optimized for low cost advantages and easy PCB Layout.
