Agilent ADNS-2030 Low Power
Optical Mouse Sensor
Data Sheet
Description
The ADNS-2030 is a low-power
optical mouse sensor used to
implement a non-mechanical
tracking engine for computer
mice. With a 3.3 V power supply
and power-saving sleep functions,
this sensor is particularly suited
to cordless mouse applications.
It is based on optical navigation
technology, which measures
changes in position by optically
acquiring sequential surface
images (frames) and mathemati-
cally determining the direction
and magnitude of movement.
The sensor is housed in a 16-pin
staggered dual inline package
(DIP) that is designed for use
with the HDNS-2100 Lens and
HDNS-2200 Clip and HLMP-
ED80-XXXXX (639 nm LED
illuminator source). There are no
moving parts, and precision
optical alignment is not required,
facilitating high volume assembly.
The output format is two channel
quadrature (X and Y direction)
which emulates encoder photo-
transistors. The current X and Y
information are also available in
registers accessed via a serial port.
Default resolution is specified as
400 counts per inch, with rates of
motion up to 14 inches per
second. Resolution can also be
programmed to 800 cpi.
The part is programmed via a
two wire serial port, through
registers.
Theory of Operation
The ADNS-2030 is based on
Optical Navigation Technology.
It contains an Image Acquisition
System (IAS), a Digital Signal
Processor (DSP) and a two
channel quadrature output, and
a two wire serial port.
The IAS acquires microscopic
surface images via the lens and
illumination system provided by
the HDNS-2100, 2200, and
HLMP-ED80-XXXXX. These
images are processed by the DSP
to determine the direction and
distance of motion. The DSP
generates the ∆x and ∆y relative
displacement values that are
converted to two channel quadra-
ture signals.
