Optimum CMOS. ET9260 Datasheet
The ET9260 is an optimum CMOS which has been designed for electronization of volume control of audio equipment,etc.
Attenuation can be controlled 0dB～－78dB by 2dB/step.
This ICs feature a builtin loudness circuit.（20dB tap）
The volume,balance and loudness circuits can be controlled by serial data.
Chip select input allows control of up to 2 of these chip on the same bus.
Polysilicon resistors enables lowdistortion,highperformance volume system.
Package is DIP16(ET9260P) and SOP16(ET9260M).
