Product Summary
The UPD3753CY is a kind of 2088-bit high sensitivity CCD (Charge Coupled Device) linear image sensor which changes optical images to electrical signal. The device includes 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. Besides, it can be driven by power supply and three input clocks owing to the built-in reset pulse generator
and a clamp pulse generator.
