Avago Technologies has expanded its optical mouse sensor line with a sensor bundle for cordless laser-based mice, and two small sensors for cordless and corded LED-based mice. The three optical navigation sensorsADNS-7050, ADNS-5030 and ADNS-5020are said to offer lower power in small packages.

A key feature of the ADNS-7050 LaserStream optical mouse sensor for cordless mice is that it can provide up to 12 months of operation using two alkaline AA cells (3V nominal). The LaserStream sensor operates on more surfaces than LED-based optical mice including painted metal, polished wood-grain, glossy photo paper, translucent plastic, frosted glass and many other previously difficult surfaces.

The ADNS-7050 sensor offers 2.7V to 3.6V operation with self-adjusting, power-saving modes for longer battery life. It provides motion detection at speeds of up to 20 inches per second (ips), acceleration of up to 8G and selectable 400 and 800 counts per inch (cpi) resolution. It also includes an adjustable frame rate, and output is a four-wire serial port with a motion-detect pin. The sensor incorporates an internal oscillator to eliminate the need for a clock input.

Supplied as a bundle to provide a complete laser-mouse tracking system, the ADNS-7050 LaserStream sensor consists of the sensor, the ADNV-6340 single-mode, vertical-cavity surface emitting laser (VCSEL), which provides up to 2kV ESD protection, a round or trim lens, and a VCSEL assembly clip. The parts interlock on a customer-designed base plate and requires no precision optical alignment during manufacturing, said the company. The LaserStream bundle provides true laser tracking performance and Class 1 eye safety.

The ADNS-5030 sensor for cordless mice is supplied in one of the industry's smallest optical sensor packages, measuring 9.9-by-12.85-by-4.32mm. The sensor's frame rate automatically adjusts based on the surface characteristics with up to 1,000cpi resolution, speeds up to 14ips, and acceleration rates of up to 2G. It provides automatic power conservation when the mouse is stationary, and includes an integrated oscillator and LED driver. The ADNS-5030 in combination with the ADNS-5100 lens, ADNS-5200 clip and HLMP-ED80 LED form a complete tracking system for wireless mice.

The ADNS-5020 for corded mice is also supplied in a small form factor package and incorporates an integrated oscillator and LED driver. The ADNS-5020 operates from 5V and features a self-adjusting frame rate with selectable 500 and 1,000cpi resolution, speeds up to 14ips, and 2G acceleration. The ADNS-5020 also mates with the ADNS-5100 lens, the ADNS-5200 clip and the HLMP-ED80 LED.

The ADNB-7051-EV (with round lens) and ADNB-7052-EV (with trim lens) bundles that incorporate the ADNS-7050 LaserStream optical mouse sensor, lens, clip and the ADNV-6340 VCSEL are priced at less than $4 each in high-volume quantities. The ADNS-5030 and the ADNS-5020 sensors for LED-based mice are priced at less than $3 each in high volumes. Samples are already available.
