Agilent ADNS-2030
Optical Mouse Sensor
Product Brief
Description
High Performance, Low Power Optical
Mouse Sensor Suitable for Cordless
Precision Optical Navigation
The ADNS-2030 is a low power
reflective optical sensor that provides
a non-mechanical tracking engine for
implementing a computer-pointing
device. It is based on optical naviga-
tion technology which measures
changes in position by optically
acquiring sequential surface images up
to 2300 times per second and math-
ematically determining the direction
and magnitude of movement at the
maximum of 800 counts per inch (cpi)
and at speeds up to 14 inches per
second (ips). Agilent provides the
complete optical mouse reference
design kit (Part # ADNK-2030). The
CMOS based sensor is mounted in a
16-pin staggered dual inline package
(DIP) and designed for use with the
HDNS-2200 (LED Assembly Clip) and
HLMP-ED80 (639 nm LED illumination
source) and HDNS-2100 (lens).
Navigation by Two Images Comparison
With its low power feature, this optical
mouse sensor enables longer battery
life and more efficient power consump-
tion. This eliminates the need for a
recharger and making it an ideal choice
for cordless optical mouse application.
Theory of Operation
The ADNS-2030 is based on Optical
Navigation Technology. It contains an
Image Acquisition System (IAS), a
Digital Signal Processor (DSP), 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. These images
are processed by the DSP to determine
the direction and distance of motion.
The DSP generates the (delta)x and
(delta)y relative displacement values
that are converted into two channel
quadrature signals.
