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.
! CMOS Technology ! Low Power Consumption ! High Operating Voltage Range : Vcc = 4 ~ 12 V (Backup Voltage is up to 4 V) ! 0dB to -34dB attenuation controlled by 1dB/step ! 2 Channels in each chip ! Capable to control attenuation by a built-in oscillator and Up/Down Pin ! Single Power Supply or Dual Power Supplies of (+) and (-) can be used ! Wide Frequency Response Range ! Very Low Harmonic Distortion ! Available in 16 pins, DIP or SO Package
