New Optical Sensors Enable Wireless Mice to Operate on a Single AA Battery for Over a Year

Avago Technologies today announced two new low-power optical sensors for wireless mouse applications.

The ADNS-2080 and ADNS-3000 LED-based sensors leverage an advanced low-power architecture and automatic power management modes to enable over a year of battery life for cordless mice using a single AA battery.

The ADNS-2080 and ADNS-3000 optical sensors provide precise, high-speed tracking for wireless mice, with high-speed motion detection of up to 30 inches per second (ips) and 20g acceleration detection. The sensors also feature selectable resolution of up to 2000 counts per inch (cpi) for accurate navigation.

The small form factor devices have on-chip oscillators, reducing external component count, and do not require precision optical alignment, facilitating high-volume assembly. These features simplify mouse designs and provide cost savings to customers.

"The ADNS-2080 and ADNS-3000 optical sensors build on this tradition with outstanding tracking performance and by enabling wireless mice to operate using only one AA battery," said Angeline Khoo, marketing manager for mouse sensor products at Avago.

In a related announcement, the company today introduced the ADNS-2700 USB optical sensor system-on-chip for simplified, cost-efficient design of corded mice.

Additional ADNS-2080 and ADNS-3000 Product Features

- Supply voltage input as low as 2.1V for the ADNS-2080 device and 1.7V for the ADNS-3000 device
- Integrated low dropout voltage regulator on the ADNS-2080 device
- External interrupt output for motion detection
- Programmable rest frame periods/response-times and downshift times from one power-saving mode to another
- Housed in 8-pin staggered dual in-line package (DIP)

The ADNS-2080 optical sensor is priced at $0.95 each for quantities up to 1,000 units and the ADNS-3000 optical sensor is priced at $0.85 each for quantities up to 1,000 units. Samples and production quantities are available now through the Avago direct sales channel and via worldwide distribution partners. Avago also offers the ADNK-2080 sample kit, the ADNK-3000 sample kit, the ADNK-2083-ND24 reference design kit, and the ADNK-3003-ND24 reference design kit for wireless mouse designers.
