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). Features l Suitable for voltage-output type image sensors l Compact (compared to conventional type C4074) l Single power supply (+12 V or +15 V) operation ■ Selection guide Type No. Product name C7885 C7885G Driver circuit Driver circuit + Pulse generator Feature High-speed driver circuit for voltage-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. 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. ■ Specifications (Ta=25 °C) Parameter Supply voltage C7885 Current consumption C7885G Operation frequency Gain Operating temperature Storage temperature * No condensation Symbol +Vs +Is G Topr Tstg Condition +12 V +12 V Master clock frequency: 3 MHz Min. +11.5 - Typ. +12.0 30 60 6 0 to +50 * -10 to +60 * Max. +15.5 40 80 500 - Unit V mA mA kHz V/V °C °C 1 Driver circuit for NMOS linear image sensor C7885 series ■ Timing chart MASTER CLOCK CLK MASTER START Start START st CLOCK CLOCK 1 2 RESET CLAMP Trigger VIDEO OUTPUT Data Video END OF SCAN EOS KACCC0120EA ■ Dimensional outlines and input/output signal descriptions (unit: mm) C7885 C7885G (4 ×) C3 (4 ×) C3 63.5 2 1 1.6 63.5 10.0 1.6 16 15 25.4 (2 ×) 3.6 25.4 7.62 50.8 7.62 (2 ×) 3.6 7.62 7.62 7.62 7.62 55.88 55.88 KACCA0086EA 2 Terminal No. 1 2 3 4 5 6 7 8 9 Terminal name A.
