Data Sheet
ADNS-2700
Single Chip USB Optical Mouse Sensor
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.
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 HLMP-EG3E-xxxxx 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.
The output format is USB. This device meets HID Revision
1.11 specification and is compatible with USB Revision 2.0
specification.
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-5100-
001 as " trim lens" and HLMP-EG3E as "LED" hereafter.

Overview of Optical Mouse Sensor Assembly
Pixart provides an IGES file drawing describing the base plate molding features for lens and PCB
alignment. The 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 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 clip holds the LED in relation to the lens. The LED must be inserted into the clip and the LED’s leads formed
prior to loading on the PCB.

Design considerations for improving ESD Performance
The table below shows typical values assuming base plate
construction per the Pixart supplied IGES
file trim lens. Stand-off of the base plate shall not be larger
than 5 mm.

should not be used as they will cause lens material defor-
mation
