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 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-2710 will be referred to as "sensor", ADNS-5110-
001 as " trim lens" and HLMP-EG3E as "LED" hereafter.

PCB Assembly Considerations
1. Insert the sensor and all other electrical components
into PCB.
2. Insert the LED into the assembly clip and bend the
leads 90 degrees.
3. Insert the LED clip assembly into PCB.
4. This sensor package is only qualified for wave-solder
process.
5. Wave solder the entire assembly in a no-wash solder
process utilizing solder fixture. The solder fixture is
needed to protect the sensor during the solder process.
It also sets the correct sensor-to-PCB distance as the
lead shoulders do not normally rest on the PCB surface.
The fixture should be designed to expose the sensor
leads to solder while shielding the optical aperture
from direct solder contact.
6. Place the lens onto the base plate.
7. Remove the protective Kapton tape from optical
aperture of the sensor. Care must be taken to keep
contaminants from entering the aperture. Recommend
not to place the PCB facing up during the entire mouse
assembly process. Recommend to hold the PCB first
vertically for the Kapton removal process.
8. Insert PCB assembly over the lens onto the base plate
aligning post to retain PCB assembly. The sensor
aperture ring should self-align to the lens.
9. The optical position reference for the PCB is set by the
base plate and lens. Note that the PCB motion due to
button presses must be minimized to maintain optical
alignment.
10. Install mouse top case. There MUST be a feature in
the top case to press down onto the PCB assembly to
ensure all components are interlocked to the correct
vertical height.
