Overview
ADNS-2080 Low Power Optical Mouse Sensor www.
DataSheet4U.
com 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 detection – 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, facilitating high volume assembly.
The sensor is programmed via registers through a twowire serial port.
It is housed in an 8-pin staggered dual in-line package (DIP).
Features x Low Power Architecture x Small Form Factor x Programmable Periods / Response Times and Downshift Times from one mode to another for the Power-saving Modes x High Speed Motion Detection up to 30 ips and 20 g x External Interrupt Output for Motion Detection x Internal Oscillator – no clock input needed x Selectable Resolution of up to 2000 cpi x Operating Voltage: as low as 2.
1 V x IO reference voltage of 1.
7 V to 3.
3 V x 2-wire serial port interface Applications x Optical mice and optical trackballs x Integrated input devices x Battery-powered input devices Theory of Operation The ADNS-2080 is based on Optical Navigation Technology, which measures changes in position by optically acquiring sequential surface images (frames) and mathematically determining the direction and magnitude of movement.
The ADNS-2080 contains an Image Acquisition System (IAS), a Digital Signal Processor (DSP), and a two wire serial port.
The IAS acquires microscopic surface images via t...
