ADNS-3080 Datasheet | Agilent Technologies

Features - High speed motion detection - up to 40 ips and 15g Description The ADNS-3080 is a high performance addition to Agilent’s popular ADNS family of optical mouse sensors. The ADNS-3080 is based on a new, faster architecture with improved navigation. The sensor is capable of sensing high speed mouse motion - up to 40 inches per second and acceleration up to 15g - for increased user precision and smoothness. The ADNS-3080 along with the ADNS-2120 (or ADNS-2120-001) lens, ADNS-2220 (or ADNS2220-001) assembly clip and HLMP-ED80-XX000 form a plete, pact optical 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. The sensor is programmed via registers through a four-wire serial port. It is packaged in a 20-pin staggered dual inline package (DIP). Theory of Operation The ADNS-3080 is based on Optical Navigation Technology, which measures changes in position by optically acquiring sequential surface images (frames) and mathematically determining the direction and magnitude of movement. - New architecture for greatly improved optical navigation technology It contains an Image Acquisition System (IAS), a Digital Signal Processor (DSP), and a four-wire serial port. The IAS acquires microscopic surface images via the lens and illumination system. These images are processed by the DSP to determine the direction and distance of motion. The DSP calculates the ∆x and ∆y relative displacement values. An external microcontroller reads the ∆x and ∆y information from the sensor serial port. The microcontroller then translates the data into PS2 or USB signals before sending them to the host PC or game console. w w w .D t a S a e h t e U 4 - Programmable frame rate over 6400 frames per second - Smart Speed self-adjusting frame rate for optimum performance - Serial port burst mode for fast data transfer - 400 or...
