WS2811 LED DRIVER CHIP, 8 PIN IC

WS2811 LED DRIVER CHIP, 8 PINS IC

The WS2811 is 3 output channels special for LED driver circuit. It internal include intelligent digital port data latch and signal reshaping amplification drive circuit. Also include a precision internal oscillator and a 12V voltage programmable constant current output drive. In the purpose of reduce power supply ripple, the 3 output channels designed to delay turn-on function. IC use single NZR communication mode. After the chip power-on reset, the DIN port receive data from controller, the first IC collect initial 24 bit data then sent to the internal data latch, the other data which reshaping by the internal signal reshaping amplification circuit sent to the next cascade IC through the DO port.

DNA solutions, Nashik has various types of IC's. Check out our complete collection of  IC's.

• Output port compression 12V. 
  

• Built in stabilivolt, Only add a resistance to IC VDD feet when under 24V power supply. 
  

• Gray level 256 can be adjusted and scan frequency not less than 400Hz/s. 
  

• Built in signal reshaping circuit, after wave reshaping to the next driver, ensure wave-form distortion not accumulate.
