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 position 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. ADNS-2610主要特性: Precise optical navigation technology Small form factor (10 mm x 12.5 mm footprint) No mechanical moving parts Complete 2D motion sensor Common interface for general purpose controller Smooth surface navigation Accurate motion up to 12 ips 400 cpi resolution High reliability High speed motion detector Wave solderable Single 5.0 volt power supply Conforms to USB suspend mode specifications Power conservation mode during times of no movement Serial port registers –Programming– Data transfer 8-pin staggered dual inline package (DIP) 应用: Mice for desktop PC’s, workstations, and portable PC’s Trackballs Integrated input devices  图1.ADNS-2610方框图  图2.ADNS-2610应用电路图 |
