Description
The ADNS-2001 is a low-cost reflective optical sensor that provides a non-mechanical tracking engine for implementing a computer mouse.

Features
• Optical navigation technology
    – Superior precision and smooth navigation optimized for desktop and portable mouse applications
    – No mechanical moving parts, provides high reliability and needs no maintenance
• Complete compact 2-D motion sensor
    – Easy implementation and design flexibility
    – Replaces mechanical ball system in traditional mice
• Two selectable output modes
    – Two channel quadrature output mode (X and Y direction) which emulates encoder phototransistors
    – Standard 3-button PS/2 output mode
• High speed motion detector
    – Accurately measures up to 16 inches per second at 400 cpi
• Accurate navigation over a wide range of surfaces
    – Enables mouse to be used with or without a mouse pad
• Power conservation mode during no motion
• Compatible with high volume manufacturing processes
    – Requires no precision optical alignment
    – Wave solderable
• 33% faster than HDNS-2000
    – 2000 fps (@ 24 MHz)

Applications
• Computer mice for desktop PCs, workstations, and portable computers
• Trackball
