The PixArt PAW3220LU-TJDU is an ultralow power and small form factor optical sensor which is optimized for infrared LED based wireless mouse applications. It has high accuracy navigation ability, low power architecture and automatic power management which make it suitable for power-sensitive application such as wireless mouse. The PAW3220LU-TJDU is capable of high-speed motion detection up to the velocity of 30 inches/sec and acceleration of 10g. 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 infrared SMT LED (LITE-ON LTEC216- P-W) and PNSR-015-RB3 optical lens.
