#155250 - settling time Responding to: ???'s previous message |
Unless you do not use the analog mux the speed of your signals is not relevant for checking against the settling time. If you want to sample several inputs you switch the ADC mux and settling time starts from scratch (actually from the previous selected input value). The ADC has only one Sample and Hold circuit, not one for each analog input. |
