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.

Notes on Bypass Capacitors
• Caps for pins 6,7 and 8 to ground MUST have trace
lengths LESS than 5 mm.
• The 0.1 uF caps must be ceramic.
• Caps should have less than 5 nH of self inductance
• Caps should have less than 0.2 ohms ESR
• Surface mount parts are recommended
Regulatory Requirements
• Passes FCC B and worldwide analogous emission limits
when assembled into a mouse with unshielded cable
and following Avago recommendations.
• Passes EN61000-4-4/IEC801-4 EFTB tests when assem-
bled into a mouse with shielded cable and following
Avago recommendations.
• UL flammability level UL94 V-0.
• Provides sufficient ESD creepage/clearance distance
to avoid discharge up to 15 kV when assembled into a
mouse according to usage instructions above.
• For eye safety consideration, please refer to the tech-
nical report available on the web site at www.Avago.

Path Error (Deviation) is the error from the ideal cursor path. It is expressed
as a percentage of total travel and is measured over standard surfaces.
The following graphs (Figures 14-18) are the typical performance of the ADNS-2620 sensor, assembled as shown in
the 2D assembly drawing with the HDNS-2100 Lens/Prism, the HDNS-2200 clip, and the HLMP-ED80-xx000 (See Figure

use with other LED colors (i.e., blue, green),
please consult factory. When using alter-
nate LEDs, there may also be performance
