ADNS-2610

Optical Mouse Sensor

Data Sheet

Description

The ADNS-2610 is a new entry level, small form ­ factor

optical mouse sensor. It is used to implement a non-

mechanical tracking engine for computer mice. ­ Unlike

its predecessor, this new optical mouse sensor allows for

more compact and affordable optical mice designs.

It is based on optical navigation technology, which mea-

sures changes in position by optically acquiring sequential

surface images (frames) and mathematically determining

the direction and magnitude of movement.

The sensor is housed in an 8-pin staggered dual inline

package (DIP). It is ­designed for use with the HDNS-2100

Lens, HLMP-ED80-XX000, and the HDNS-2200 LED Clip,

providing an optical mouse solution that is compact and

affordable. There are no moving parts, so precision opti-

cal alignment is not required, thereby facilitating high

volume assembly.

The output format is a two wire serial port. The current X

and Y information are available in registers accessed via

the serial port.

Resolution is 400 counts per inch (cpi) with rates of motion

up to 12 inches per second (ips).

Theory of Operation

The ADNS-2610 is based on Optical Navigation Technol-

ogy. It contains an Image Acquisition System (IAS), a Digi-

tal Signal Processor (DSP) and a two wire ­serial port.

The IAS acquires microscopic surface images via the lens

and illumination system provided by the HDNS-2100,

HDNS-2200, and HLMP-ED80-XX000. These images are

processed by the DSP to determine the direction and

distance of motion.
