IMAGE SENSOR Driver circuit for CMOS linear image sensor C9001 Compact, easy-to-use driver circuit C9001 is a driver circuit designed for S8377/S8378 series CMOS linear image sensors. C9001 operates a linear image sensor by just inputting two signals (clock and start) and a single +5 V supply. C9001 also outputs a trigger signal for A/D conversion so the external circuit configuration can be simplified. C9001 does not include an image sensor, so select the desired image sensor and order it separately.

The sensor is scanned in synchronization with this signal. Sensor scan start signal. The pulse interval of these start signals determines the sensor integration I time. Sensor gain setting. Low gain is selected at High level, and high gain at Low level. (External I gain setting is enabled with S2.) O Sensor end-of-scan signal. Negative logic O A/D conversion timing signal. The number of output pulses is equal to the number of pixels. Circuit ground I +5 V power supply line Circuit ground O Video output signal. Positive polarity Video signal ground is supplied with C9001 along with to a cable (30 cm, preassembled). Information furnished by HAMAMATSU is believed to be reliable.
