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.
