High-precision driver circuit for current-output type NMOS linear image sensor

C7884 series is a driver circuit specifically designed for the Hamamatsu current-output type NMOS linear image sensors (S3901 to S3904 series, S8380/S8381 series). NMOS linear image sensors are self-scanning photodiode arrays integrated with a scanning circuit of N-channel MOS transistors.

C7884 series supplies start pulses and 2-phase clock pulses necessary for image sensor operation. C7884 series also includes a signal processing circuit to read out video signals from an image sensor in the electric charge accumulation mode. C7884 series operates by input of a master start pulse, master clock pulse and connection to double power supply (±12 V or ±15 V).

Features

• High-precision operation (compared to C7883 series)

• Low noise (compared to C7883 series)

• Compact (compared to conventional type C4070)

• Double power supply (±12 V or ±15 V) operation
