Resolution Calculator for Model DI-2108-P
How much ADC Resolution Do You Really Need for your Measurements?
The bit value of an analog-to-digital converter (ADC) refers directly to its resolution. The resolution determines how finely it slices its full-scale measurement range, or in other words, the smallest change in the input signal that it can theoretically measure (ignoring noise). Use the calculator below to determine if the DI-2108-P has enough ADC resolution to meet your application requirements. Review the blog post How Much ADC Resolution Do You Really Need? for more information.

1 Assuming the use of the R250 Shunt Resistor (recommended). A different shunt resistor will produce different results.
2 Choose a Channel Gain Range based on the closest available value to your sensor output range. For example, if the output range of your sensor is 0-10 Volts you should choose the 0-10 Volt Gain Range. Smaller gain ranges may be used if the effective measurement range is known (see Gain and Dynamic Range Considerations for more information). 4-20mA and 0-20mA outputs should use the 0-5 Volt Gain Range.
