SOP8 DMX512 IC Components

Short Description:

This pixel protocol, also known as DMX512P, It uses a non-differential DMX512 protocol to drive pixel chips. The control circuit comes in a SOP8 package, allowing for more flexibility with LED choice.

DMX512 Advantages

  • High PWM rate allows for filming these pixels with cameras up to 100fps
  • Up to 24V, allowing for very long cable lengths
  • Presence of white LED allows for higher brightness and more color mixing options

DMX512 Disadvantages

  • Data-only restricts refresh rates to be limited by the speed of the protocol, which will generally be slow
  • Only 8 bits of data for each color makes dimming curves less smooth
  • No redundancy in data
