Overview
ADNS-2030 Low Power Optical Mouse Sensor Data Sheet Description The ADNS-2030 is a low-power optical mouse sensor used to implement a non-mechanical tracking engine for computer mice.
With a 3.
3 V power supply and power-saving sleep functions, this sensor is particularly suited to cordless mouse applications.
It 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 sensor is housed in a 16-pin staggered dual inline package (DIP) that is designed for use with the HDNS‑2100 Lens and HDNS‑2200 Clip and HLMP-ED80-XX000 (639 nm LED illuminator source).
There are no moving parts, and precision optical alignment is not required, facilitating high volume assembly.
The output format is two channel quadrature (X and Y direction) which emulates encoder photo-transistors.
The current X and Y information are also available in registers accessed via a serial port.
Default resolution is specified as 400 counts per inch, with rates of motion up to 14 inches per second.
Resolution can also be programmed to 800 cpi.
The part is programmed via a two wire serial port, through registers.
Theory of Operation The ADNS-2030 is based on Optical Navigation Technology.
It contains an Image Acquisition System (IAS), a Digital Signal Processor (DSP) and 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, HDNS-2200 and HLMP-ED80-XX000.
These images are processed by the DSP to determine the direction and distance of motion.
The DSP generates the ∆x and ∆y relative displacement values that are converted to two channel quadrature signals.
