APPLICATION NOTE 1141
Adding Global Intensity Control to the MAX6956 and MAX6957 Static
LED Drivers
Abstract: This application note discusses techniques to change the intensity of all the LED segments of a display
at once (global intensity control) driven by the MAX6956 or MAX6957 static LED drivers. This control is
additional to the segment-by-segment adjustment the drivers offer already. The note includes a calculator in
the form of an Excel spreadsheet that may be downloaded to assist design.
