Description
The ADNS-3080 is a high performance addition to Avago
Technologies’ popular ADNS family of optical mouse
sensors.
The ADNS-3080 is based on a new, faster architecture with
improved navigation. The sensor is capable of sensing high
speed mouse motion - up to 40 inches per second and
acceleration up to 15g – for increased user precision and
smoothness.
The ADNS-3080 along with the ADNS-2120 (or ADNS-2120-
001) lens, ADNS-2220 (or ADNS-2220-001) assembly clip and
HLMP-ED80-XX000 form a complete, compact optical mouse
tracking system. There are no moving parts, which means
high reliability and less maintenance for the end user. In
addition, precision optical alignment is not required, facilitat-
ing high volume assembly.
The sensor is programmed via registers through a four-wire
serial port. It is packaged in a 20-pin staggered dual inline
package (DIP).
Theory of Operation
The ADNS-3080 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.
It contains an Image Acquisition 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 images are processed
by the DSP to determine the direction and distance of
motion. The DSP calculates the ∆x and ∆y relative dis-
placement values.
An external microcontroller reads the ∆x and ∆y informa-
tion from the sensor serial port. The microcontroller then
translates the data into PS2 or USB signals before sending
them to the host PC or game console.
