Dither on MC43?

Kevin 5 years ago in IQANdesign • updated by Gustav Widén (System support) 5 years ago • 1

Many years ago we used to have dither control on COUT's, but this was removed a while back i believe. We have an application that requires some dither control on some current outputs from an MC43, can anyone suggest a good way of integrating it? I cant see anything that points towards dither frequency (only PWM frequency) in the module configuration settings?

After adding the COUT to the MC4x/XC4x module, you find the property for the PWM frequency on the pin in the block diagram. 

The PWM frequency will be your dither frequency.
