ADNS-2001 Datasheet | Agilent Technologies

Description The ADNS-2001 is a low-cost reflective optical sensor that provides a non-mechanical tracking engine for implementing a puter mouse. It is based on optical navigation technology which measures changes in position by optically acquiring sequential surface images (frames) and mathematically 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 plete and pact 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 - plete pact 2-D motion sensor - Easy implementation and design flexibility - Replaces mechanical ball system in traditional mice w w w .D - Two selectable output modes - Two channel quadrature output mode (X and Y direction) which emulates encoder phototransistors - Standard 3-button PS/2 output mode t a S a e h t e U 4 - Power conservation mode during no motion - patible with high volume manufacturing processes - Requires no precision optical alignment - Wave solderable - 33% faster than HDNS-2000 - 2000 fps (@ 24 MHz) Applications - puter mice for desktop PCs, workstations, and portable puters - Trackball - Integrated input devices .c m o h S a to prevent Caution: It is advised that normal static precautions be taken in handling and assembly of this ponent damage and/or degradation which may be induced by ESD. at .D w w w t e e 4U . m o c Theory of Operation The ADNS-2001...
