Low Power Optical Mouse Sensor

Data Sheet

Description

The Avago Technologies ADNS-5030 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-5030 is capable of high-speed motion

detection – up to 14 ips and 2G. In addition, it has an

on-chip oscillator and LED driver to minimize external

components.

The ADNS-5030 along with the ADNS-5100/ADNS-5100-

001 lens, ADNS-5200 clip, and HLMP-ED80 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 housed in an 8-pin staggered dual

in-line package (DIP).

Theory of Operation

The ADNS-5030 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-5030 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 dis-

placement values.

An external microcontroller reads the Dx and Dy informa-

tion from the sensor serial port. The microcontroller then

translates the data into PS2, USB, or RF signals before

sending them to the host PC.
