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.
