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

l High-precision operation (compared to C7883 series)

l Low noise (compared to C7883 series)

l Compact (compared to conventional type C4070)

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