Adding Global Intensity Control to the MAX6956 and MAX6957 Static LED Drivers


摘要 : 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.
