ADNS-3080光流传感器芯片详细资料文件

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.

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.

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.

Features

• High speed motion detection – up to 40 ips and 15g

• Four-wire serial port along with Chip Select, Power

Down, and Reset pins

Applications

• Mice for game consoles and computer games

• Mice for desktop PC’s, Workstations, and portable

PC’s

• Trackballs

• Integrated input devices

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 ange 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
