The ADNS-5020-EN is capable of high-speed motion detection up to 20 ips and 2G. In addition, it has an onchip oscillator and built-in LED driver to minimize external components. Frame rate is also adjusted internally. The ADNS-5020-EN along with the ADNS-5100/ADNS5100-001 lens, ADNS-5200 clip and HLMP-ED80 LED form a complete and compact mouse tracking system. There are no moving parts, which means high reliability and less maintenance for the end user. In addition, precision optical alignment is not required, facilitating high volume assembly.
