1. Overview

Functional Block Diagram and Operation

ADNS-5712 is an USB1.1 Full Speed interfaced mouse sensor with a CMOS-processed image sensor, mixed-mode analog front-end

circuits, integrated digital image processing circuits and versatile digital functional circuits for various mouse applications. It is based on an

optical navigation technology which measures changes in position by optically acquiring sequential surface images (frames) and

mathematically determining the speed, the direction and the magnitude of motion. The displacement delta_X and delta_Y information are

available in registers which are accessible through USB interface.
