ADNS-3050 Datasheet | PixArt

Description Features The Pixart ADNS-3050 is a small form factor entry-level gaming optical navigation sensor. It is housed in an 8-pin staggered dual in-line package (DIP). It is capable of high-speed motion detection typically at 60ips and acceleration up to 20g; suitable for both wired and wireless gaming navigation system. The low power management in wireless mode can be customized to suit user preferences. In addition, it has an on-chip oscillator and LED driver to minimize external ponents. The ADNS-3050 sensor along with the ADNS-5110-001 lens, PS"%/4trim MFOTLED clip, and HLMP-EG3E red LED forms a plete and pact mouse tracking system. There are no moving parts, which translates to high reliability and less maintenance for the end user. Precision optical alignment is not required, thus facilitating high volume assembly. - Small Form Factor Package - 8-pin DIP - Operating Voltage: 2.8V-3.0V - High Speed Motion Detection at typical of 60ips and acceleration up to 20g. - Selectable Resolutions up to 2000cpi - Four wire Serial Port Interface - External Interrupt Output for Motion Detection - Internal Oscillator - no clock input needed - On-chip LED driver - Minimal number of passive ponents - Programmable power-saving modes for selectable wired or wireless application - Customizable response time and downshift time for rest modes Theory of Operation - Configurable LED operating modes and drive current The ADNS-3050 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-3050 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 ΔX and Δy...
