AMIS-710208-A7: 200dpi Module
AMIS-710208-A7 (PI208MC-A7) contact image sensor (CIS) module containing contact image sensors, using image sensor technology high-speed performance high sensitivity. AMIS-710208-A7 designed scan documents with short read length 88mm. module produces single stream sampled analog video proportional images single horizontal line scan that stepped vertically down document page with resolution dots millimeter (dpm) width 88mm. Applications include machines, game systems, variety mark readers, other automation equipment requiring document scanners.
Features
Light source, lens sensor integrated into single module 8dpm resolution, 88mm scanning length 176µsec/line scanning speed, with 4MHz pixel rate (see Table Note Wide dynamic range 660nm light source Compact size 13mm 25.6mm 102mm Low-power Light weight
Functional Description
AMIS-710208-A7 imaging array consists AMIS-720233 (PI3033B) sensors, produced AMIS, which cascaded together provide photo-detectors (pixels) with their associated multiplex switches, digital shift register that controls sequential readout. Each sensor sequentially connected initiate scanning process completion predecessor's scan. Mounted module one-to-one graded-indexed micro lens array that focuses image scanned onto linear array pixels. incident image converted electrical signal then charge each pixel transferred common video line. charge each pixel then converted voltage single video amplifier. module output then available connector, Vout. Illumination means integrated light source. components housed small plastic housing which cover glass that acts focal point object being scanned. addition, protects imaging array, micro lens assembly light source from dust. Inputs outputs (I/O's) from module 8-pin connector, located module. cross-section AMIS-710208-A7 module shown Figure block diagram Figure

"GAIN ADJUST" used change analog gain. This used average video output (Vpavg) particular level when different exposure levels employed. Vpavg factory with particular exposure level. Note that exposure product light power time exposure (integration time). Since module's light power constant, then total light exposure then depends integration time, which time between Start Pulses (SP). integration time factory usually according customer requirements; Vpavg then adjusted particular level. From this level, integration time decreased increased, specified Vpavg will increase decrease proportionally. necessary restore amplitude, within limited range, adjusted with gain control.
