PT2256
DESCRIPTION
PT2256 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. PT2256 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 package and is functionally compatible with TC9235P. Pin assignments
and application circuit are optimized for low cost advantages and easy PCB Layout.
FEATURES
