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. Features l High-speed operation (compared to C7884) l Compact (compared to conventional type C4069) l Single power supply (+12 V or +15 V) operation ■ Selection guide Type No. Product name C7883 Driver circuit C7883G Driver circuit + Pulse generator Feature High-speed driver circuit for current-output type NMOS linear image sensors. Has no input/output connector. A dedicated pulse generator is pre-mounted on the driver circuit board. Has no input/output connector. C7883 driver circuit board is installed in a shield case. C7883-20 Multichannel detector head 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), 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. ■ Specifications (Ta=25 °C) Parameter Supply voltage Current consumption Operation frequency Gain Operating temperature Storage temperature * No condensation Symbol +Vs C7883 C7883G C7883-20 +Is G Topr Tstg Condition +12 V +12 V +12 V Master clock frequency: 8 MHz Min. +11.5 - Typ. +12.0 30 60 30 24 0 to +50 * -10 to +60 * Max. +15.5 40 80 40 2 - Unit V mA mA mA MHz kV/A °C °C 1 Driver circuit for NMOS linear image sensor C7883 series ■ Timing chart MASTER CLOCK CLK MASTER START Start START st CLOCK 1 CLOCK 2 Trigger VIDEO OUTPUT Data Video END OF SCAN EOS KACCC0118EA ■ Dimensional outlines and input/output signal descriptions (unit: mm) C7883 55.88 1.6 63.5 10.0 1.6 16 15 25.4 2 1 (4 ×) C3 (2 ×) 3.6 15.2 15.24 7.62 7.62 40.64 (2 ×) 3.6 25.4 (4 ×) C3 C7883G 7.62 7.62 7.62 7.62 55.88 63.5 KACCA0085EA 2 Terminal No. 1 2 3 4 5 6 7 8 9 Terminal name A.
