1 / 26 page  Agilent ADNS-3040 Ultra Low-Power Mouse Sensor Data Sheet Description The ADNS-3040 is an ultra low-power optical navigation sensor. It has a new, low- power architecture and automatic 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 detection – up to 20 ips and 8G. In addition, it has an on-chip oscillator and LED driver to minimize external components. The ADNS-3040 along with the ADNS-3120-001 lens, ADNS- 2220 clip and HLMP-ED80- PS000 LED form a complete and compact mouse tracking system. There are no moving parts, which means 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 four-wire serial port. It is packaged in a 20-pin DIP. Theory of Operation The ADNS-3040 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-3040 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 ∆x and ∆y relative displacement values. An external microcontroller reads the ∆x and ∆y information from the sensor serial port. The microcontroller then translates the data into PS2, USB, or RF signals before sending them to the host PC or game console.
