IMAGE SENSOR
Driver circuit for NMOS linear image sensor
C7885 series
Driver circuit for voltage-output type NMOS linear image sensor
C7885
C7885 series is a driver circuit specifically designed for the Hamamatsu voltage-output type NMOS linear image sensors (S3921 to S3924
series). NMOS linear image sensors are self-scanning photodiode arrays integrated with a scanning circuit of N-channel MOS transistors.
C7885 series supplies start pulses, 2-phase clock pulses and reset pulses necessary for voltage-output type image sensor operation. C7885
series also includes a signal processing circuit that inverts and amplifies video signals from an image sensor. C7885 series operates by input of a
master start pulse, master clock pulse and connection to a power supply (+12 V or +15 V).

Note)
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), C7885 will be shipped with a mating connector pre-mounted.
4: We welcome custom requests. Feel free to contact our sales office.
5: When using current-output type NMOS linear image sensors, refer to C7883/C7884 series data sheets.

Note) When making a simple in-circuit evaluation of NMOS linear image sensors without any troublesome soldering, use
C7883G, C7884G, C7884G-01 or G7885G in combination with A8226.
All you have to do is just insert an NMOS linear image sensor into the socket and connect the cables to an oscilloscope,
power supply and AD converter. Note that NMOS linear image sensors are sold separately.
