2660 PIXELS CCD LINEAR IMAGE SENSOR

The µPD3734A is a high sensitivity CCD (Charge Coupled Device) linear image sensor which changes optical images to electrical signal.

The µPD3734A has 2660 pixels and an output amplifier which has high gain and wide output range, but low noise.

Built-in sample and hold circuit converts and outputs independent signal from CCD register in every pixel to continuous video signal. So it is easy to interface to A/D converter or Bi-level converter.
