ADNS-2610Optical Mouse Sensor
The ADNS-2610 is a new entry level, small form factor optical mouse sensor. It is used to implement a non-mechanical tracking engine for computer mice. Unlike its predecessor, this new optical mouse sensor allows for more compact and affordable optical mice designs.
It is based on optical navigation technology, which mea¬sures changes in POSTTTION by optically acquiring sequential surface images (frames) and mathematically determining the direction and magnitude of movement.
The sensor is housed in an 8-pin staggered dual inline package (DIP). It is designed for use with the HDNS-2100 Lens, HLMP-ED80-xx000, and the HDNS-2200 LED Clip, providing an optical mouse solution that is compact and affordable. There are no moving parts, so precision opti¬cal alignment is not required, thereby facilitating high volume assembly.
The output format is a two wire serial port. The current X and Y information are available in registers accessed via the serial port.
Resolution is 400 counts per inch (cpi) with rates of motion up to 12 inches per second (ips).
Theory of Operation
The ADNS-2610 is based on Optical Navigation Technol¬ogy. It contains an Image Acquisition System (IAS), a Digital Signal Processor (DSP) and a two wire serial port.
The IAS acquires microscopic surface images via the lens and illumination system provided by the HDNS-2100, HDNS-2200, and HLMP-ED80-xx000. These images are processed by the DSP to determine the direction and distance of motion.
