Data Sheet ADNS-2710 Single Chip USB Optical Mouse Sensor Description The ADNS-2710 is a compact, one chip USB optical mouse sensor designed for implementation of a non-mechanical tracking engine in computer mice. It is based on optical navigation technology that measures changes in position by optically acquiring sequential surface images (frames) and mathematically determining the direction and magnitude of movement. The sensor is in an 8-pin optical package that is designed to be used with the ADNS-5110-001 trim lensPS "%/4MFOTBOEUIF)-.1&(&3FE-&% Together, these parts provide a complete BOEDPNQBDU mouse sensor. There are no moving parts BOEQSFDJTJPO optical alignment is not required, thus faciliUBUJOH high volume assembly. The output format is USB. This device me [ ... ]
