ADNS-2080
Low Power Optical Mouse Sensor
Data Sheet
Description
The Avago Technologies ADNS-2080 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-2080 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-2080 along with the ADNS-5110-001 lens,
ADNS-5200 clip, and HSDL-4261 IR LED, or HLMP-EG3E
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, fa-
cilitating high volume assembly.
The sensor is programmed via registers through a two-
wire serial port. It is housed in an 8-pin staggered dual
in-line package (DIP).
