TCD2252D

The TCD2252D is designed as a high sensitive and low dark current 2700 elements x3 lines CCD color image sensor which is for color scanner.

TCD2252D has eight features. (1)Number of image sensing elements is 2700 elements x3 lines. (2)Image sensing element size is 8um by 8um on 8um centers. (3)Photo sensing region is high sensitive and low dark current pn photodiode. (4)Distance between photodiode array is 64um (8 lines). (5)Clock 2 phase (5V). (6)Internal circuit sample&hold circuit, clamp circuit. (7)Package is 22 pin DPI CERDIP package. (8)Color filter is red, green, blue. Those are all the main features.

Some absolute maximum ratings of TCD2252D have been concluded into several points as follow. (1)Its clock pulse voltage would be from -0.3V to 8V. (2)Its shift pulse voltage would be from -0.3V to 8V. (3)Its reset pulse voltage would be from -0.3V to 8V. (4)Its sample and hold pulse voltage would be from -0.3V to 8V. (5)Its clamp pulse voltage would be from -0.3V to 8V. (6)Its power supply voltage would be from -0.3V to 15V. (7)Its operating temperature range would be from 0°C to 60°C. (8)Its storage temperature range would be from -25°C to 85°C. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of TCD2252D are concluded as follow. (1)Its sensitivity (red) would be typ 7.0V. (2)Its sensitivity green would be typ 9.1V. (3)Its sensitivity blue would be typ 3.2V. (4)Its photo response non uniformity would be typ 10% and max 20%. (5)Its saturation output voltage would be min 3.0V and typ 3.2V. (6)Its saturation exposure would be typ 0.35lxs. (7)Its dark signal voltage would be typ 2.0mV and max 6.0mV. And so on.
