DATA SHEET

The

µPD3753 is a 2088-bit high sensitivity CCD (Charge Coupled Device) linear image sensor which

changes optical images to electrical signal.

The

µPD3753 consists of 2088-bit photocell array and a line of 2088-bit CCD charge transferred register.

It contains a reset a feed-through level clamp circuit, a pulse generator, and a voltage amplifier to provide

high sensitivity and low noise. It also supports low power consumption with single 5 V power supply. The

µPD3753 can be driven by power supply and three input clocks owing to the built-in reset pulse generator

and a clamp pulse generator.
