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 (鹵12 V or 鹵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.
