Data Sheet

The ADNS-2700 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-5100-001 trim lens, LED clip and the LED. Together, these parts provide a complete and compact mouse sensor. There are no moving parts and precision optical alignment is not required, thus facilitating high volume assembly.

Frame rate is varied internally to the sensor to achieve tracking and speed performance, eliminating the need for the use of many registers.

Default resolution is specified as 1000 counts per inch, with rates of motion up to 30 inches per second.

A complete mouse can be built with the addition of a PC board, switches and Z-wheel, plastic case and cable.

NOTE ADNS-2700 will be referred to as "sensor", ADNS-5100001 as " trim lens" and HLMP-EG3E as "LED" hereafter.

Theory of Operation

The sensor 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 trim lens. The clip and LED. These images are processed by the DSP to determine the direction and distance of motion. The DSP generates the and relative displacement values which are converted to USB motion data.
