Wireless mouse IC PAW3805EK-CJV2 Track On Glass Mouse Sensor

General Description

The PixArt PAW3805EK-CJV2 is an optical sensor which is

optimized for blue LED based wireless mouse application.

It has high accuracy navigation ability that enables

navigation virtually on any flat surface, including the

transparent glass. The low power architecture and

automatic power management make it suitable for

power-sensitive application such as a wireless mouse.

PAW3805EK-CJV2 is capable of high-speed motion

detection up to the velocity of 40 inches/sec and 10g on

non-glass surfaces, 20 inches/sec and acceleration of 5g

on glass surface. In addition, it has an on-chip oscillator

and a built-in programmable LED current driver. In order

to achieve the best tracking performance, it is

recommended to match the sensor with L029-SSI optical

lens.
