ET9260
ET9260 is Optimum CMOS manufactured by Etek Microelectronics.
General Description The ET9260 is an optimum CMOS which has been designed for electronization of volume control of audio equipment,etc.
Features
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).
