ADNS-3050 Entry-level Gaming Optical Navigation Sensor
Data Sheet
ADNS-3050
Description
The
Pixart
ADNS-3050 is a small form factor
entry-level
gaming optical navigation sensor. It is housed
in an 8-pin staggered dual in-line package (DIP). It is ca-
pable of high-speed motion detection typically at 60ips
and acceleration up to 20g; suitable for both wired and
wireless gaming navigation system. The low power man-
agement in wireless mode can be customized to suit user
preferences. In addition, it has an on-chip oscillator and
LED driver to minimize external components.
The ADNS-3050 sensor along with the ADNS-5110-001
lens,
trim
LED clip, and HLMP-EG3E
red LED forms a complete and compact mouse tracking
system. There are no moving parts, which translates to
high reliability and less maintenance for the end user.
Precision optical alignment is not required, thus facilitating
high volume assembly.

Theory of Operation
The ADNS-3050 is based on Optical Navigation Technol-
ogy, which measures changes in position by optically
acquiring sequential surface images (frames) and math-
ematically determining the direction and magnitude of
movement. The ADNS-3050 contains an Image Acquisi-
tion System (IAS), a Digital Signal Processor (DSP), and a
four wire serial port. The IAS acquires microscopic surface
images via the lens and illumination system. These im-
ages are processed by the DSP to determine the direction
and distance of motion. The DSP calculates the ΔX and Δy
relative displacement values. An external microcontroller
reads and translates the ΔX and Δy information from the
sensor serial port into PS2, USB, or RF signals before send-
ing them to the host PC.
Applications
Wired and Wireless Optical gaming mice and trackballs
Integrated input devices
Battery-powered input devices
NOTE: The ADNS-3050 sensor is not designed for use with blue
LED navigation system.
