How would I go about calculating the sampling rate of an ADC with only an input frequency and a conversion rate? Also, how would I calculate the minimum and maximum sampling rate?

What is the make and part number of the ADC?

The maximum sampling rate would be stated in the datasheet of the ADC.
The minimum sampling rate of an ADC is 0Hz.

If your input signal is a sine wave, the minimum sampling rate would be two times the frequency of the sine wave, according to the Nyquist (sampling) theorem.

For any signal other than a pure sine wave, the minimum sampling rate would be twice the frequency of the highest frequency component in the signal.
