TCD2704D
The TCD2704D is a high sensitive and low dark current 7500
elements × 4 line CCD color image sensor which includes CCD
drive circuit, clamp circuit.
The sensor is designed for scanner. The device contains a row of
7500 elements × 4 line photodiodes which provide a 24 lines/mm
across a A3 size paper. The device is operated by 5 V pulse and
12 V power supply.
