I am uncertain how to use the Muxxed current feedback on the 4 channel part if i have a 1khz drive frequency. if the switching time is 50us (have to switch 4 times to get all outputs), then you can get a sample of each channel every 200us (5khz) assuming instant ADC reading. that leaves only 5 samples per PWM frequency which is likley to alias with a inductive load. If you add a filter to the output of the sense, then the settling time will be impacted significantly where you are likley getting less than 1khz of readings. Is there an example usage of how to drive an inductive load with this part?
