ADNS-4700

Single Chip USB Optical Mouse Sensor

Data Sheet

Description

The ADNS-4700 is a compact, one chip USB optical mouse

sensor designed for implementation of a non-mechanical

tracking engine in computer mice.

It is based on optical navigation technology that measures

changes in position by optically acquiring sequential

surface images (frames) and mathematically determining

the direction and magnitude of movement.

The sensor is in an 8-pin optical package that is designed

to be used with the ADNS-5110-001 trim lens, the

ADNS-5200 clip, and the HLMP-CB3A Blue LED. Together,

these parts provide a complete and compact mouse

sensor. There are no moving parts and precision optical

alignment is not required, thus facilitating high volume

assembly.

The output format is USB. This device meets HID Revision

1.11 specifi cation and is compatible with USB Revision 2.0

specifi cation.

Frame rate is varied internally to the sensor to achieve

tracking and speed performance, eliminating the need for

the use of many registers.

Default resolution is specifi ed as 1000 counts per inch,

with rates of motion up to 30 inches per second.

A complete mouse can be built with the addition of a PC

board, switches and Z-wheel, plastic case and cable.

NOTE: ADNS-4700 will be referred to as "sensor", ADNS-5110-

001 as " trim lens", ADNS-5200 as "clip" and HLMP-CB3A as "LED"

hereafter.
