MAX6973 - (MAX6972 / MAX6973) 16-Output PWM LED Drivers

Download the MAX6973 datasheet PDF. This datasheet also covers the MAX6972 variant, as both devices belong to the same (max6972 / max6973) 16-output pwm led drivers family and are provided as variant models within a single manufacturer datasheet.

General Description

The MAX6972/MAX6973 precision current-sinking, 16-output PWM LED drivers drive red, green, and/or blue LEDs for full-color graphic message boards and video displays.

Key Features

  • 16 LED Current Sink Outputs (Two Banks of Eight Outputs).
  • 32 LED Drive Option When Multiplexing.
  • 33MHz Clock Supports Up to 63 Frames per Second of Video.
  • Constant Output Current Calibration from 11mA to 55mA in 256 Steps.
  • EZCascade™ Interface Simplifies Multiple Driver Cascading Without External Buffers.
  • 12-Bit or 14-Bit Individual PWM LED Intensity Controls.
  • 7-Bit or 5-Bit Panel PWM-Intensity Control.
  • +3V to +7V LED Power.
