Agilent ADNS-2030 Optical Mouse Sensor Product Overview Features • • • • • • Description High Performance, Low Power Optical Mouse Sensor Suitable for Cordless Precision Optical Navigation The ADNS-2030 is a low power reflective optical sensor that provides a non-mechanical tracking engine for implementing a computer-pointing device. 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 800 counts per inch (cpi) and at speeds up to 14 inches per second (ips). Agilent provides the complete optical mouse sample kit (Part # ADNK-2030). The CMOS based sensor is mounted in a 16-pin staggered dual inline package (DIP) and designed for use with the HDNS-2200 (LED Assembly Clip) and HLMP-ED80XXXXX (639 nm LED illumination source) and HDNS-2100 (lens). With its low power feature, this optical mouse sensor enables longer battery life and more efficient power consumption. This eliminates the need for a recharger and making it an ideal choice for cordless optical mouse application. Theory of Operation The ADNS-2030 is based on Optical Navigation Technology. It contains an Image Acquisition System (IAS), a Digital Signal Processor (DSP), a two-channel quadrature output, and a two-wire serial port. The IAS acquires microscopic surface images via the lens and illumination system provided by the HDNS-2100, 2200, and HLMP-ED80-XXXXX. These images are processed by the DSP to determine the direction and distance of motion. The DSP generates the (delta)x and (delta)y relative displacement values that are converted into two channel quadrature signals.
