ADNS-3080

Data Sheet ADNS-3080 High-Performance Optical Mouse Sensor Description The ADNS-3080 is a high performance addition to PixArt Imaging popular ADNS family of optical mouse sensors. The ADNS-3080 is based on a new, faster architecture with improved navigation. The sensor is capable of sensing high speed mouse motion - up to 40 inches per second and acceleration up to 15g – for increased user precision and smoothness. The ADNS-3080 along with the ADNS-2120-001 trim lens, ADNS-2220-001 assembly clip and HLMP-EG3E-xxxxx led form a complete, compact optical mouse tracking system. There are no moving parts, which means high reliability and less maintenance for the end user. In addition, precision optical alignment is not required, facilitating high volume assembly. The sensor is programmed via registers through a four-wire serial port. It is packaged in a 20-pin staggered dual inline package (DIP). Theory of Operation The ADNS-3080 is based on Optical Navigation Technology, which measures changes in position by optically acquiring sequential surface images (frames) and mathematically determining the direction and magnitude of movement. It contains an Image Acquisition System (IAS), a Digital Signal Processor (DSP), and a four-wire serial port. The IAS acquires microscopic surface images via the lens and illumination system. These images are processed by the DSP to determine the direction and distance of motion. The DSP calculates the Δx and Δy relative displacement values. An exte...
