FEATURES
● Low power architecture DESCRIPTION
In addition, it has an on-chip oscillator and LED driver to minimize external components. The ADNS-3040 along with the ADNS-3120-001 lens, ADNS2220 clip and HLMP-ED80PS000 LED form a complete and compact 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. Theory of Operation The ADNS-3040 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. The ADNS-3040 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.
