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.
