com Optical Mouse Sensor Data Sheet Description The ADNS-5050 is a mainstream, small form factor optical mouse sensor.
It is a user-friendly product with many built-in features and optimized for LED-based corded products.
The ADNS-5050 is capable of high-speed motion detection – up to 30ips and 8g.
In addition, it has an on-chip oscillator and built-in LED driver to minimize external components.
Frame rate is also adjusted internally.
The ADNS-5050 along with the ADNS-5100/5100-001 lens, ADNS-5200 clip and HLMP-ED80 LED form a complete and compact mouse tracking system.
There are no moving parts, which mean 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 threewire SPI interface.
It is housed in an 8-pin staggered dual in-line package (DIP).
Features • Small form factor, ADNS-5020-EN pin-to-pin compatible with • Register-to-register compatible with ADNS-5020-EN • Built-in LED driver for simpler circuitry • High speed motion detection at 30 ips and up to 8g • Self-adjusting frame rate for optimum performance • Internal oscillator – no clock input needed • Default 500 cpi resolution, adjustable from 125 to 1375 cpi via 125 cpi step • Operating voltage: 5V nominal • Three-wire serial interface • Only 4 capacitors and no transistor required Applications • Optical Mice • Optical trackballs • Integrated input devices Theory of Operation The ADNS-5050 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-5050 contains an Image Acquisition System (IAS), a Digital Signal Processor (DSP), and a three wire serial port.
The IAS acquires microscopic surface images via the lens and illumination system.
These images are processe...
