µPD3753
Monochrome
2088 Pixels CCD Linear Image Sensor
Overview
The µPD3753 is a 2088-pixel high sensitivity CCD (Charge Coupled Device) linear image sensor which changes optical images to electrical signal.
The µPD3753 consists of 2088-pixel photocell array and a line of 2088-pixel CCD charge transferred register.
It contains a reset a feed-through level clamp circuit, a reset pulse generator, a clamp 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.
