TCD2557D

The TCD2557D is designed as a high sensitive and low dark current 5340 elements x3 lines CCD image sensor which includes CCD drive circuit, clamp circuit and sample and hold circuit.

TCD2557D has nine features. (1)Number of image sensing elements 5340 elements x3 lines. (2)Image sensing element size 7um by 7um on 7um centers. (3)Photo sensing region is high sensitive pn photodiode. (4)Clock is 2 phase (5V). (5)Package is 22 pin CERDIP. (6)Distance between photodiode array is 28um (4 lines). (7)Internal circuit is sample and hold circuit, clamp circuit. (8)Color filter is red, green and blue. (9)Power supply is 12V power supply voltage. Those are all the main features.

Some absolute maximum ratings of TCD2557D have been concluded into several points as follow. (1)Its colck 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 clamp pulse voltage would be from -0.3v to 8V. (5)Its power supply voltage would be from -0.3V to 15V. (6)Its operating temperature range would be from 0°C to 60°C. (7)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.
