World's smallest optical mouse sensor

World's smallest optical mouse sensor Avago Avago announced the launch of the world's smallest optical mouse sensor, the ADNS-2700, which integrates optical sensors and controllers into a compact, highly integrated SoC system-on-chip that greatly simplifies positioning devices such as mice and trackballs. The internal structure.

The ADNS-2700 integrates an LED optical sensor (IAS image acquisition system), a digital signal processor (DSP), and a USB stream output circuit in an 8 pin DIP packaged SoC chip with an area of ​​only 9.9x9.1 mm. It also includes a crystal frequency generator. With load resistors, multiple external components can be eliminated and the mouse structure can be simplified. The chip contains a one-time programming storage space, manufacturers can write manufacturer identification information, set the mouse resolution, sensor orientation and so on.

The sensor does not require precise positioning and can be easily assembled on a large scale. The resolution is 250 to 1250CPI, the maximum speed is 30 inches per second, and the maximum acceleration is 8G. The ADNS-2700 will ship in batches starting today, and the unit price will be 0.75 US dollars.

At the same time, Avago also introduced two low-power optical sensor products ADNS-2080 and ADNS-3000 specifically designed for wireless mice. The operating voltages are 2.1V and 1.7V, respectively. They use their wireless mouse products as a AA battery. It can be used for more than one year, and the specifications can still reach a resolution of up to 2000 cpi, 30 inches per second and 20G acceleration. The 1,000 unit price of the two chips is 0.95 and 0.85 USD, respectively.
