Optical Mouse Sensor

Data Sheet

Description

The ADNS-2001 is a low-cost

reflective optical sensor that

provides a non-mechanical

tracking engine for implementing a

computer mouse.

It is based on optical navigation

technology which measures

changes in position by optically

acquiring sequential surface

images (frames) and mathematic-

ally determining the direction and

magnitude of movement. The

sensor is mounted in a plastic

optical package and designed to be

used with the HDNS-2100 (Lens),

HDNS-2200 (LED Assembly Clip)

and HLMP-ED80 (High Light

Output 639 nm LED), providing a

complete and compact tracking

engine. This optical tracking

engine has no moving parts and

requires no precision optical

alignment enabling high volume

system assembly. The ADNS-2001

offers a PS/2 or quadrature output

mode for interface flexibility.

Resolution is specified as 400 cpi

at rates of motion up to 16 inches

per second.

Features

• Optical navigation technology

– Superior precision and smooth

navigation optimized for

desktop and portable mouse

applications

– No mechanical moving parts,

provides high reliability and

needs no maintenance

• Complete compact 2-D motion

sensor

– Easy implementation and

design flexibility

– Replaces mechanical ball

system in traditional mice

• Two selectable output modes

– Two channel quadrature output

mode (X and Y direction) which

emulates encoder

phototransistors

– Standard 3-button PS/2 output

mode

• High speed motion detector

– Accurately measures up to

16 inches per second at 400 cpi

• Accurate navigation over a wide

range of surfaces

– Enables mouse to be used with

or without a mouse pad

• Power conservation mode during

no motion

• Compatible with high volume

manufacturing processes

– Requires no precision optical

alignment

– Wave solderable

• 33% faster than HDNS-2000

– 2000 fps (@ 24 MHz)

Applications

• Computer mice for desktop PCs,

workstations, and portable

computers

• Trackball

• Integrated input devices

Caution: It is advised that normal static precautions be taken in handling and assembly of this component to prevent

damage and/or degradation which may be induced by ESD.
