ADNS-2030

Low Power Optical Mouse Sensor

Data Sheet

Description

The ADNS-2030 is a low-power optical mouse sensor used

to implement a non-mechanical tracking engine for com-

puter mice. With a 3.3 V power supply and power-saving

sleep functions, this sensor is particularly suited to cord-

less mouse applications.

It is based on optical navigation technology, which mea-

sures changes in position by optically acquiring sequen-

tial surface images (frames) and mathematically deter-

mining the direction and magnitude of movement.

The sensor is housed in a 16-pin staggered dual inline pack-

age (DIP) that is designed for use with the HDNS‑2100 Lens

and HDNS‑2200 Clip and HLMP-ED80-XX000 (639 nm LED

illuminator source). There are no moving parts, and precision

optical alignment is not required, facilitating high volume

assembly.

The output format is two channel quadrature (X and Y direc-

tion) which emulates encoder photo-transistors. The current

X and Y information are also available in registers accessed

via a serial port.

Default resolution is specified as 400 counts per inch,

with rates of motion up to 14 inches per second. Resolu-

tion can also be programmed to 800 cpi.

The part is programmed via a two wire serial port,

through registers.

Theory of Operation

The ADNS-2030 is based on Optical Navigation Technol-

ogy. It contains an Image Acquisition System (IAS), a Digi-

tal Signal Processor (DSP) and a two channel quadrature

output, and a two wire serial port.

The IAS acquires microscopic surface images via the lens

and illumination system provided by the HDNS-2100,

HDNS-2200 and HLMP-ED80-XX000. These images are

processed by the DSP to determine the direction and dis-

tance of motion. The DSP generates the ∆x and ∆y relative

displacement values that are converted to two channel

quadrature signals.
