Low Power LED Integrated Slim Mouse Sensor
Data Sheet
The ADNS-3530 LED optical mouse sensor is a small form
factor (SFF) LED illuminated navigation system.
The ADNS-3530 is a low-power optical navigation sen-
sor. 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
The ADNS-3530 is capable of high-speed motion
detection — up to 20 ips and 8 g. In addition, it has
an on-chip oscillator and integrated LED to minimize
external components.
The ADNS-3530, along with the ADNS-3150-001 lens,
forms a complete and compact mouse tracking system.
There are no moving parts which means high reliabil-
ity 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 16 I/O surface mount-
able package.
Theory of Operation
The ADNS-3530 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
The ADNS-3530 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
Δx and Δy relative
displacement values.
An external microcontroller reads the
Δx and Δy infor-
mation from the sensor serial port. The microcontroller
then translates the data into PS2, USB, or RF signals
0before sending them to the host PC or game console.
