When is the analog input sampled?

i.e. in what time period are the switches in Figure 45 closed?

Thanks for any help you can provide

Hello Henning,

The sampling switch on this device remains closed whenever the ADC is not converting. A rising edge on the CONVST pin causes the sampling switch to open and the ADC begins converting the (last) analog input value held across the internal sample-and-hold capacitor.
