Small Form Factor, Entry-Level Optical Mouse Sensor with Performance Features

The ADNS-2620 is a new entry level, small form factor optical mouse sensor. It is used to implement a non-mechanical tracking engine in computer mice. Unlike its predecessor, this new optical mouse sensor allows for more compact and affordable optical mouse designs.

It is based on optical navigation technology which measures changes in position by optically acquiring sequential surface images up to 2300 times per second and mathematically determining the direction and magnitude of movement at the maximum of 400 counts per inch (cpi)and at speeds up to 12 inches per second (ips).

Avago Technologies provides the complete optical mouse sample kit (Part #ADNK-2620). The CMOS based sensor is mounted in an 8-pin staggered dual inline package (DIP)and designed foruse with the HDNS-2200 (LED Assembly Clip)and HLMP-ED80- XXXXX (639 nm LED illumination source) and HDNS-2100 (lens).There are no moving parts, so precision optical alignment is not required, thereby facilitating high volume assembly.
