ADNS-3040 Summary of contents
Page 1
... It has a new, low-power architecture and auto- matic power management modes, making it ideal for battery-and power-sensitive applications such as cordless input devices. The ADNS-3040 is capable of high-speed motion detec- tion – ips and 8g. In addition, it has an on-chip oscillator and LED driver to minimize external compo- nents. ...

... Theory of Operation The ADNS-3040 is based on Optical Navigation Technol- ogy, which measures changes in position by optically acquiring sequential surface images (frames) and math- ematically 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 ...

... PCB alignment. The components interlock as they are mounted onto defined features on the base plate. The ADNS-3040 sensor is designed for mounting on a through-hole PCB, looking down. There is an aperture stop and features on the package that align to the lens. The ADNS-3120-001 lens provides optics for the imaging of the surface as well as illumination of the surface at the 12 ...

... ADNS-3040 will flash the LED only when needed. Synchronous Serial Port The synchronous serial port is used to set and read pa- rameters in the ADNS-3040, and to read out the motion information. The port is a four wire serial port. The host micro-con- troller always initiates communication; the ADNS-3040 never initiates data transfers ...
