ADNS-2710
Single Chip USB Optical Mouse Sensor
Data Sheet
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 lens
Together, these parts provide a complete
mouse sensor. There are no moving parts
optical alignment is not required, thus facili
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.
