Electronic Volume Controller IC

PT2257

DESCRIPTION

PT2257 is an Electronic Volume Controller IC utilizing CMOS Technology specially designed for the

new generation of AV Entertainment Products. It has two (2) built-in channels making it ideally suit-

able for mono and stereo sound applications. PT2257 provides an I

C Control Interface, an attenuation

range of 0 to -79 dB, low noise, high channel separation. Housed in 8-pin, DIP or SO Package,

PT2257’s pin assignments and application circuit are optimized for easy PCB Layout and cost saving

advantages.
