Optical Mouse Sensor

Data Sheet

Description

Features

The ADNS-5050 is a mainstream, small form factor opti-  Small form factor, pin-to-pin compatible with

cal mouse sensor. It is a user-friendly product with many

built-in features and optimized for LED-based corded

products.

ADNS-5020-EN

 Register-to-register compatible with ADNS-5020-EN

 Built-in LED driver for simpler circuitry

 High speed motion detection at 30 ips and up to 8g

 Self-adjusting frame rate for optimum performance

 Internal oscillator – no clock input needed

The ADNS-5050 is capable of high-speed motion detec-

tion – up to 30ips and 8g. In addition, it has an on-chip

oscillator and built-in LED driver to minimize external

components. Frame rate is also adjusted internally.

The ADNS-5050 along with the 5100-001 lens, LED clip  Default 500 cpi resolution, adjustable from 125 to 1375

and HLMP-EG3E-xxxxx LED form a complete and com-

pact mouse tracking system. There are no moving parts,

which mean high reliability and less maintenance for the

end user. In addition, precision optical alignment is not

required, facilitating high volume assembly.

cpi via 125 cpi step

 Operating voltage: 5V nominal

 Three-wire serial interface

 Only 4 capacitors and no transistor required

The sensor is programmed via registers through a three-

wire SPI interface. It is housed in an 8-pin staggered dual

in-line package (DIP).

Applications

 Optical Mice

 Optical trackballs

 Integrated input devices

Theory of Operation

The ADNS-5050 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

movement.

The ADNS-5050 contains an Image Acquisition System

(IAS), a Digital Signal Processor (DSP), and a three wire se-

rial 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 mo-

tion. The DSP calculates the Δx and Δy relative displace-

ment values.

An external microcontroller reads the Δx and Δy informa-

tion from the sensor serial port. The microcontroller then

translates the data into PS2 or USB signals before sending

them to the host PC.
