ADNS-2051

Optical Mouse Sensor

Data Sheet

Description

The ADNS-2051 is a low cost optical sensor used to

implement a non-mechanical tracking engine for

computer mice.

It is based on optical navigation technology, which

measures changes in position by optically acquiring

sequential surface images (frames) and mathemati-

cally determining the direction and magnitude of

movement.

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

package (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, fa-

cilitating high volume assembly.

The output format is two channel quadrature (X and Y

direction) 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

(cpi), with rates of motion up to 14 inches per second

(ips).

Resolution can also be programmed to 800 cpi.

The part is programmed via a two wire serial port,

through registers.

Theory of Operation

The ADNS-2051 is based on Optical Navigation Tech-

nology. It contains an Image Acquisition System (IAS), a

Digital Signal Processor (DSP), 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,

2200, and HLMP-ED80-XX000 LED. These images are

processed by the DSP to determine the direction and

distance of motion. The DSP generates the Δx and Δy

relative displacement values that are converted into two

channel quadrature signals.
