APPLICATION NOTE 1148
Adding Global LED Intensity Control to the MAX6954 and MAX6955
LED Drivers
Abstract:This application note discusses techniques to simultaneously change the intensity (i.e., global intensity control) of all the
LED digits of a display that is driven by the MAX6954 or MAX6955 multiplexed LED drivers. This global control is additional to
the digit-by-digit adjustment that the drivers offer already. The note includes a spreadsheet calculator to assist design.
This application note discusses a technique for adding global LED intensity control to the MAX6954 and MAX6955 LED drivers.
