Optical Mouse Sensor Data Sheet Description The ADNS-2620 is a new entry level, small form ­ factor optical mouse sensor. It is used to implement a nonmechanical tracking engine for puter mice. ­ Unlike its predecessor, this new optical mouse sensor allows for more pact and affordable optical mice designs. It 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. The sensor is housed in an 8-pin staggered dual inline package (DIP). It is designed for use with the HDNS-2100 Lens, HLMP-ED80-xx000, and the HDNS-2200 LED Clip, providing an optical mouse solution that is pact and affordable. There are no moving parts, so precision optical alignment is not required, thereby facilitating high volume assembly. The output format is a two wire serial port. The ­current X and Y information are available in ­registers accessed via the serial port. Resolution is 400 counts per inch (cpi) with rates of motion up to 12 inches per second (ips). Theory of Operation The ADNS-2620 is based on Optical Navigation ­Technology. It contains an Image Acquisition System (IAS), a Digital Signal Processor (DSP) and a two wire serial port. The IAS acquires microscopic surface images via the lens and illumination system provided by the HDNS-2100, HDNS-2200, and HLMP-ED80-xx000. These images are processed by the DSP to determine the direction and distance of motion.
