ADNS-5030
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.
