Low power optical sensor ADNS-2080 and ADNS for wireless mouse

Avago Technologies has announced two new low-power optical sensors for wireless mice. The ADNS-2080 and ADNS-3000 LED sensors use an advanced low-power architecture and automatic power management mode to enable wireless mice to operate for up to a year on a single AA battery.

The ADNS-2080 and ADNS-3000 optical sensors provide precise, high-speed tracking for wireless mice, detecting up to 30 inches per second (ips) of motion and 20g of acceleration. The sensors also feature selectable resolutions up to 2000 cpi for extremely precise and sensitive navigation.

The small package with a monolithic oscillator reduces the number of external components and eliminates the need for precision optical alignment, making it easier to assemble in high volumes. These features simplify mouse design and can save costs for consumers.

"This device's improved tracking performance while reducing power consumption lays the foundation for our dominance in the optical mouse sensor space," said Angeline Khoo, product marketing manager for mouse sensors at Avago. "The ADNS-2080 and ADNS-3000 optical sensors build on this foundation, delivering superior tracking performance and enabling wireless mice to operate on a single AA battery."

In a separate announcement announcing the breadth of the Avago optical mouse sensor portfolio, the company today announced the launch of the highly integrated ADNS-2700 USB optical sensor system-on-chip for simple and economical wired mouse designs.

Optical navigation technology

The latest sensors measure position changes by capturing continuous images of a surface through optical signals and performing mathematical operations on the changes in the image to determine the direction and magnitude of movement. These devices are equipped with an image acquisition system (IAS), a digital signal processor (DSP), and in addition, a two-wire serial port for the ADNS-2080 and a four-wire serial port for the ADNS-3000. The DSP automatically processes the images from the IAS to determine the direction and distance of movement, without the mouse designer having to deal with source code or firmware. The serial port allows these devices to be programmed through registers.

Avago is a pioneer in optical navigation technology, which you can now find in many of the mice used around the world. To date, Avago has sold over one billion optical navigation sensors to a wide range of customers around the world.
