ADNS-3080
High-Performance Optical Mouse Sensor
Data Sheet
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-2120-001 trim lens,
ADNS-2220-001 assembly clip and HLMP-EG3E-xxxxx led
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, facilitating 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 Δx and Δy relative dis-
placement values.
An external microcontroller reads the Δx and Δy 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.

Overview of Optical Mouse Sensor Assembly
2D Assembly Drawing of ADNS-3080
Shown with ADNS-2120-001 trim lens, ADNS-2220-001
assembly clip and HLMP-EG3E-xxxxx led.
Avago Technologies provides an IGES file drawing de-
scribing the base plate molding features for lens and PCB
alignment.
The components interlock as they are mounted onto
defined features on the base plate.
The ADNS-3080 sensor is designed for mounting on a
through hole PCB, looking down. There is an aperture
stop and features on the package that align to the lens.
The ADNS-2120-001 trim lens provides optics for the
imaging of the surface as well as illumination of the
surface at the optimum angle. Features on the lens
align it to the sensor, base plate, and clip with the LED.
The lens also has a large round flange to provide a long
creepage path for any ESD events that occur at the
opening of the base plate.
The ADNS-2220-001 clip holds the LED in relation to
the lens. The LED must be inserted into the clip and the
LED’s leads formed prior to loading on the PCB. The clip
interlocks the sensor to the lens, and through the lens to
the alignment features on the base plate.
The HLMP-EG3E-xxxxx LED is recommended for illumina-
tion. If used with the bin table, sufficient illumination can
be guaranteed.
