ADNS-2620
Optical Mouse Sensor
Data Sheet
Description
The ADNS-2620 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 solu-
tion that is compact and affordable. There are no moving
parts, so precision optical 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-2620 is based on Optical Navigation
­Technology. It contains an Image Acquisition System
(IAS), a Digital 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 direc-
tion and distance of motion.
