1 / 39 page  Description The ADNS-3080 is a high performance addition to Avago Technologies’ 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 (or ADNS-2120- 001) lens, ADNS-2220 (or ADNS-2220-001) assembly clip and HLMP-ED80-XX000 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, facilitat- ing 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 Technol- ogy, which measures changes in position by optically acquiring sequential surface images (frames) and math- ematically 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 ∆x and ∆y relative dis- placement values. An external microcontroller reads the ∆x and ∆y informa- tion from the sensor serial port. The microcontroller then translates the data into PS2 or USB signals before sending them to the host PC or game console.
