Product Overview
Avago Tech ADNS-3080 is a high-performance optical navigation sensor IC housed in a 20-pin staggered dual in-line package. Built around an internal image acquisition system and digital signal processor, the chip measures surface displacement by acquiring micro-images of the surface and calculating relative motion vectors. It communicates movement data across a standard four-wire serial SPI interface.
Key Features
- Selectable resolution of 400 or 1600 counts per inch (cpi)
- High-speed motion detection up to 40 inches per second (ips) and 15g acceleration
- Programmable frame rate up to 6,400 frames per second with automatic rate adjustment
- 4-wire serial port interface compatible with SPI protocol
- Operates on 3.3V nominal supply voltage (2.7V to 3.6V range)
- 20-pin dual in-line plastic package with integrated bottom optical aperture
- On-chip oscillator and motion-detect interrupt output
Applications
- Restoring or modifying precision optical computer gaming mice and trackballs
- Optical flow odometry and surface displacement sensing on autonomous mobile robotics
- Position tracking on low-altitude drone flight control platforms
- Non-contact XY surface measurement and maker motion sensing projects
Frequently Asked Questions
What supply voltage does the ADNS-3080 require?
The sensor operates on a nominal 3.3V DC supply, with an acceptable operating range between 2.7V and 3.6V.
What interface is used to read motion data?
Movement data and internal registers are accessed through a four-wire serial interface compatible with SPI.
What package footprint does this sensor use?
It uses a 20-pin staggered DIP package with through-hole leads and a circular optical port on the bottom of the body.
Before specialized camera modules took over maker navigation, chips like the ADNS-3080 mapped the tabletop one pixel cluster at a time. Wire it to an SPI header and let real surface displacement steer your build.
