ADNS-2080: Low Power Optical Mouse Sensor

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).
