ADNS-5050 Optical Mouse Sensor

Data Sheet

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 5100-001 lens, LED clip and 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 .

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.
