IMAGE SENSOR
Driver circuit for NMOS linear image sensor
C7883 series
High-speed driver circuit for current-output type NMOS linear image sensor
C7883
C7883 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.
C7883 series supplies start pulses and 2-phase clock pulses necessary for image sensor operation. C7883 series also includes a signal
processing circuit to read out video signals from an image sensor in the current-to-voltage conversion mode.
C7883 series operates by input of a master start pulse, master clock pulse and connection to a power supply (+12 V or +15 V).
C7883-20 is multichannel detector head incorporating driver circuit (C7883) developed for Hamamatsu NMOS linear image sensor. C7883-20 is
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.

1: Standard input/output connector is FAP-16-07#2 (made by Yamaichi, sold separately). Equivalent connectors are available
from other manufacturers.
2: Custom products with an input/output connector pre-mounted are available on request. Please consult our sales office.
3: When ordering along with a dedicated cable (A8226), C7883 series will be shipped with a mating connector pre-mounted.
4: We welcome custom requests (e.g. 4 MHz high-speed type). Feel free to contact our sales office.
5: When high precision measurements are required, refer to C7884 series data sheet.
6: When using voltage-output type NMOS linear image sensors, refer to C7885 series data sheet.
