... ADNS-2700 Single Chip USB Optical Mouse Sensor Data Sheet Description The ADNS-2700 is a compact, one chip USB optical mouse sensor designed for implementation of a non-mechanical tracking engine in computer mice 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 ...

... Theory of Operation The ADNS-2700 is based on Optical Navigation Technology. It contains an Image Acquisition System (IAS), a Digital Signal Processor (DSP) and USB stream output. The IAS acquires microscopic surface images via the lens and illumination system provided by the ADNS-5100 round lens or ADNS-5100-001 trim lens. The ADNS-5200 clip and HLMP-EG3E-XXXXX ...

... Avago Technologies provides an IGES file drawing de scribing the base plate molding features for lens and PCB alignment. The ADNS-2700 sensor is designed for mounting on a through-hole PCB. There is an aperture stop and features on the package that align to the lens. The ADNS-5100-xxx lens provides optics for the imaging of the surface as well as the illumination of the surface at the optimum angle. Features on the lens align it to the sensor, base plate, and clip with the LED. The ADNS-5200 clip holds the LED in relation to the lens. The LED must be inserted into the clip and the LED’ ...
