TC221, TC225, TC227 SMALL-FORMAT CCD IMAGE SENSORS SOCS037C – DECEMBER 1991 – REVISED AUGUST 1997 Full-Frame Operation – 190 (H) × 190 (V) Active Elements for TC221 – 285 (H) × 285 (V) Active Elements for TC225 – 102 (H) × 102 (V) Active Elements for TC227 Dark-Reference Pixels 9-m Square Pixels Single-Phase Clocking Low Dark Current Dynamic Range . . . More Than 60 dB High Photoresponse Uniformity High Sensitivity Low-Noise Operation Solid State Reliability With No Residual Imaging, Image Burn-In, Microphonics, or Image Distortion TC225 TRG SRG1 SRG2 ABG IAG 1 2 3 4 5 10 9 8 7 6 SUB OUT1 OUT2 ADB NC NC – No internal connection TC221 description The TC221, TC225 and TC227 are full-frame charge-coupled device (CCD) image sensors designed specifically for medical and industrial applications where ruggedness and small size are required. The image-area diagonal measures 1.3 mm for the TC227, 2.4 mm for the TC221, and 3.63 mm for the TC225. The image sensors contain, in addition to dark reference pixels, 190, 285, and 102 active lines with 190, 285, and 102 active pixels per line, respectively. The antiblooming feature is activated by supplying clock pulses to the antiblooming gate, an integral part of each image-sensing element. The charge is converted to signal voltage at 9.5 V per electron by a high-performance structure with built-in automatic reset and a voltage-reference generator. The signal is further buffered by a low-noise two-stage source-follower amp……
