The latest version of the Java Applet Plugin is required to run this design tool. No special issues are known to exist with the Analog Multiplexer Settling-time Calculator at this time. Tabbing from one field to the other updates the tabular display at right, or click "Calculate". To use the calculator, enter the multiplexer parameters in R ON, C S and C D and the application parameters in R SOURCE, R LOAD and C LOAD. The maximum sampling frequency estimate is shown in megasamples/second to the right of the settling time number. This number should be less than the sum of t ACQ+t CONV, otherwise the maximum sampling frequency will be limited by the latter. The sampling rate is estimated as 1/sqrt( (t settle+t transition) 2 + t PGA 2). The Analog Multiplexer Settling-Time Calculator also estimates the maximum sampling rate possible for a classic A/D converter with S/H input. This calculator estimates settling time for a multiplexer by calculating the slower of the two time constants for a cascaded RC network, then computing how many of that time constant must pass before the system will settle to within 1%, 0.1%, 0.01% and 0.001% of its final value. ![]()
