ET2256 - optimum CMOS IC

General Description

The ET2256 is an optimum CMOS IC which has been designed for electronization of volume control of audio equipment, etc.

Key Features

  • Attenuation can be controlled from 0dB to ­78dB by up, down input. This IC have 20dB tap for loudness circuit. This IC features a built­in DC output circuit (7 level) for volume level meter. Polysilicon resistors enable low­distortion, high­performance volume systems. Volume level remains in backup mode with low current consumption. Package is DIP16 (ET9235P) and SOP16W (ET9235M).
