image sensor ingaas linear image sensor near infrared image sensor (0.9 to 1.7 m) with high-speed data rate g9494-256d/-512d hamamatsu provides high-speed, near infrared image sensors designed for detectors used in on-line foreign object inspection equ ipment. these image sensors use square-shaped pixels that are ideally suited for software processing in pattern recognition systems. the signal processing circuit employs ctia (capacitive transfer impedance amplifier) method to perform simultaneous charge inte gration on all pixels, so there is no time lag among the pixel output signals. features l high-speed data rate: 2 mhz typ. l selectable conversion gain (cf=0.1 pf, 1 pf) l pixel size g9494-256d: 50 50 m g9494-512d: 25 25 m l cmos readout circuit incorporated l low dark current l room temperature operation applications l foreign object detection monitors l near infrared spectroscopy 1 selection guide type no. cooling number of pixels pixel pitch (m ) pixel size [ m (h ) m (v)] spectral response range ( m ) defective pixel g9494-256d 256 50 50 50 g9494-512d non-cooled 512 25 25 25 0.9 to 1.7 (25 c) less than 1 % absolute maximum ratings p aram eter symbol value unit supply voltage vdd -0.3 to +6 v clock pulse voltage v -0.3 to + 6 v reset pulse voltage v (res) -0.3 to +6 v g a in se lec tion te rm in a l volta ge vcf sel -0.3 to + 6 v operating temperature * 1 topr -20 to +70 c storage temperature * 1 ts tg -20 to +85 c *1: no condensation electrical characteristics (ta=25 c) p aram eter symbol min. typ. max. unit g9494-256d 4.5 5.0 5.5 supply voltage g9494-512d vdd 4.5 5.0 5.5 v supply voltage vref - 1.26 - v g9494-256d - 40 75 supply current g9494-512d i vdd - 80 150 ma i vref - - 1 ma supply current i in p - - 1 ma ground vss - 0 - v elem ent bias in p 3.3 3.5 3.6 v clock frequency f 0.1 2 4 mhz high 4.5 5.0 5.5 clock pulse voltage low v - 0 0.4 v c lock pulse rise / fall tim es tr , tf 0 20 100 ns clock pulse width tpw 100 - - ns high 4.5 5.0 5.5 reset pulse voltage low v (res) - 0 0.4 v r eset pulse rise / fall tim es tr (r e s ), tf (res) 0 20 100 ns reset pulse width * 2 tpw (res) 6/f - - s high v h - 3.5 in p video output voltage low v l - 1.26 - v video output impedance zv - 5 - k ? high - vdd - a/d trigger voltage vtrig low - gnd - v a/d trigger drive function vad 74hc244 1 ch - - - d ata rate fv - f - hz *2: 6 s or more
