Agilent ADNS-2001
Optical Mouse Sensor
Data Sheet
omDescription
.cThe ADNS-2001 is a low-cost
reflective optical sensor that
provides a non-mechanical
Utracking engine for implementing a
t4computer mouse.
It is based on optical navigation
etechnology which measures
changes in position by optically
eacquiring sequential surface
himages (frames) and mathematic-
ally determining the direction and
Smagnitude of movement. The
sensor is mounted in a plastic
taoptical package and designed to be
used with the HDNS-2100 (Lens),
aHDNS-2200 (LED Assembly Clip)
and HLMP-ED80 (High Light
.DOutput 639 nm LED), providing a
complete and compact tracking
engine. This optical tracking
wengine has no moving parts and
requires no precision optical
walignment enabling high volume
system assembly. The ADNS-2001
moffers a PS/2 or quadrature output
w omode for interface flexibility.
.cResolution is specified as 400 cpi
Uat rates of motion up to 16 inches
t4per second.
Features
• Optical navigation technology
– Superior precision and smooth
navigation optimized for
desktop and portable mouse
applications
– No mechanical moving parts,
provides high reliability and
needs no maintenance
• Complete compact 2-D motion
sensor
– Easy implementation and
design flexibility
– Replaces mechanical ball
system in traditional mice
• Two selectable output modes
– Two channel quadrature output
mode (X and Y direction) which
emulates encoder
phototransistors
– Standard 3-button PS/2 output
mode
• High speed motion detector
– Accurately measures up to
16 inches per second at 400 cpi
• Accurate navigation over a wide
range of surfaces
– Enables mouse to be used with
or without a mouse pad
• Power conservation mode during
no motion
• Compatible with high volume
manufacturing processes
– Requires no precision optical
alignment
– Wave solderable
• 33% faster than HDNS-2000
– 2000 fps (@ 24 MHz)
Applications
• Computer mice for desktop PCs,
workstations, and portable
computers
• Trackball
• Integrated input devices
taSheeCaution: It is advised that normal static precautions be taken in handling and assembly of this component to prevent
www.Dadamage and/or degradation which may be induced by ESD.

Notes:
1. Due to the Cypress implementation of USB suspend mode support, the NRESET pin of the ADNS-2001 must be reset using a line from the Cypress
chip. The reason for this is that the Cypress chip does not configure the port input pins until after it has received a bus reset from the USB port.
The unconfigured input port pins present a 16 KΩ pullup to VCC. If a cap is used on NRESET (pin 15), this pullup will result in the ADNS-2001
seeing a high on the MODE pin and powering up in the PS/2 mode.
2. The quadrature input pins of the Cypress part must be programmed to be Hi-Z, instead of the normal current pulldowns. This ensures that the
ADNS-2001 will be able to pull the quadrature lines high over all conditions of voltage and temperature.
3. 0.1 µF between pins 7 and 8 must be ceramic, and must be trace lengths less than 5 mm.
