ADNS-3000 Low Power Optical Mouse Sensor

Data Sheet

The Avago Technologies ADNS-3000 is a low power, small form factor optical mouse sensor. It has a new low-power architecture and automatic power management modes, making it ideal for battery, power-sensitive applications such as cordless input devices.

The ADNS-3000 is capable of high-speed motion detection up to 30 ips and 20 g. In addition, it has an on-chip oscillator and requires an external resistor to set the LED current.

The ADNS-3000 along with the ADNS-5110-001 lens, and HSDL-4261 IR LED or Red LED form a complete and compact mouse tracking system. There are no moving parts and this translates to 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 fourwire serial port. It is housed in an 8-pin staggered dual in-line package DIP .

Theory of Operation

The ADNS-3000 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-3000 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 Dx and Dy relative displacement values

An external microcontroller reads and translates the Dx and Dy information from the sensor serial port into PS2, USB, or RF signals before sending them to the host PC.
