ADNS-5700
Optical Mouse Sensor
Data Sheet
Description
The ADNS-5700-XXXX is a compact, one chip USB optical
mouse sensor for implementing a non-mechanical track-
ing engine for 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 a 18 -pin optical package that is designed
to be used with the ADNS-5100-001 trim lens the ADNS-
5200 Clip and the HLMP-EG3E-xxxxx LED. These parts
provide a complete and compact mouse sensor. There are
no moving parts, and precision optical alignment is not
required, facilitating high volume assembly.
The output format is USB. This device meets HID Revision
1.11 speci cation and is compatible with USB Revision 2.0
speci cation.
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 speci ed as 1000 counts per inch,
with rates of motion up to 30 inches per second. Buttons
and tilt wheel features are also available.
A complete mouse can be built with the addition of a PC
board, switches and mechanical Z-wheel, plastic case and
cable.
Theory of Operation
The ADNS-5700-XXXX 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-
001 trim lens, ADNS-5200 clip and HLMP-EG3E-xxxxx LED.
These images are processed by the DSP to determine the
direction and distance of motion. The DSP generates the
x and y relative displacement values which are converted
to USB motion data.
