LINEAR IMAGE SENSOR IC FOR CIS
S-8632AWI
The S-8632AWI is a suitable linear image sensor IC for a multichip-type contact image sensor with a resolution of 300 dots per inch. This IC integrates a 96dots photo-diode array and a CMOS scanning circuit. Picture signals are output one after another in analog signals, synchronized with a clock signal.
