Data Sheet
ADNS-3000
Low Power Optical Mouse Sensor
Description
The PixArt Imaging ADNS-3000 is a low power, small
form factor optical mouse sensor. It has a new low-power
architecture and automatic power management modes,
making it ideal for battery, power-sensitive applications –
such as cordless input devices.
The ADNS-3000 is capable of high-speed motion detec-
tion – up to 30 ips and 20 g. In addition, it has an on-chip
oscillator and requires an external resistor to set the LED
current.
The ADNS-3000 along with the ADNS-5110-001 lens,
or ADNS-5120-002 trim lens and HSDL-4261 IR LED or
HLMP-EG3E-xxxxx Red LED
form a complete and compact mouse tracking system.
There are no moving parts and this translates to
high reliability and less maintenance for the end user.
In addition, precision optical alignment is not required,
facilitating high volume assembly.
The sensor is programmed via registers through a four-
wire serial port. It is housed in an 8-pin staggered dual
in-line package (DIP).
