| IMAGE SENSOR Driver circuit for NMOS linear image sensor C7884 series High-precision driver circuit for current-output type NMOS linear image sensor C7884 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). C7884-20 and C7884-21 are multichannel detector heads incorporating driver circuit (C7884, C7884-01) developed for Hamamatsu NMOS linear image sensor. C7884-20 and C7884-21 are designed especially for compactness, having an overall length as short as 40 mm or less. The housing case also provides a shielding effect against external noise. As useful options, peripheral devices are available for driving C7884-20 and C7884-21, and for the output signal processing. 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 I Selection guide Type No. C7884 Product name Driver circuit Feature High precision driver circuit for current-output type NMOS linear image sensors.
