WS2811 3-Channel Addressable RGB LED Driver IC – SOP-8 – Constant Current

The WS2811 SOP-8 is a widely used 3-channel constant-current RGB LED driver IC designed for creating fully addressable LED lighting systems. This compact SOP-8 surface-mount package enables precise control of RGB LEDs using a single-wire NZR communication protocol, making it ideal for LED strips, pixel modules, and full-color display systems.

Offering 256 gray levels per channel, the WS2811 delivers a full 24-bit color depth, enabling over 16 million vivid colors. Its constant-current output ensures uniform brightness and color accuracy across all LEDs, even with supply voltage fluctuations. Each device includes internal signal reshaping and amplification, ensuring reliable data transmission across long LED chains.

With support for various input voltage configurations (chip operating range 6V–7V, application circuits 5V–24V), the WS2811 provides exceptional flexibility for decorative lighting, signage, and high-resolution LED display systems.
