Agilent ADNS-2001
Optical Mouse Sensor
Data Sheet
•
High speed motion detector
– Accurately measures up to
16 inches per second at 400 cpi
•
Accurate navigation over a wide
range of surfaces
Description
Features
– Enables mouse to be used with
or without a mouse pad
The ADNS-2001 is a low-cost
reflective optical sensor that
provides a non-mechanical
tracking engine for implementing a
computer mouse.
•
Optical navigation technology
– Superior precision and smooth
navigation optimized for
desktop and portable mouse
applications
•
•
Power conservation mode during
no motion
Compatible with high volume
manufacturing processes
– Requires no precision optical
alignment
– No mechanical moving parts,
provides high reliability and
needs no maintenance
It is based on optical navigation
technology which measures
– Wave solderable
changes in position by optically
acquiring sequential surface
images (frames) and mathematic-
ally determining the direction and
magnitude of movement. The
sensor is mounted in a plastic
optical package and designed to be
used with the HDNS-2100 (Lens),
HDNS-2200 (LED Assembly Clip)
and HLMP-ED80 (High Light
Output 639 nm LED), providing a
complete and compact tracking
engine. This optical tracking
engine has no moving parts and
requires no precision optical
alignment enabling high volume
system assembly. The ADNS-2001
offers a PS/2 or quadrature output
mode for interface flexibility.
Resolution is specified as 400 cpi
at rates of motion up to 16 inches
per second.
•
•
Complete compact 2-D motion
sensor
– Easy implementation and
design flexibility
– Replaces mechanical ball
system in traditional mice
•
33% faster than HDNS-2000
– 2000 fps (@ 24 MHz)
Applications
•
Computer mice for desktop PCs,
workstations, and portable
computers
Two selectable output modes
– Two channel quadrature output
mode (X and Y direction) which
emulates encoder
•
•
Trackball
phototransistors
– Standard 3-button PS/2 output
mode
Integrated input devices
Caution: It is advised that normal static precautions be taken in handling and assembly of this component to prevent
damage and/or degradation which may be induced by ESD.
