ET9235
ET9235 is Optimum CMOS IC manufactured by Etek Microelectronics.
General Description The ET9235 is an optimum CMOS IC which has been designed for electronization of volume control of audio equipment, etc.
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)、SOP16FJ(ET9235M)、SOP16(ET9235)
