#123371 - Some advantages
Responding to: ???'s previous message
Without knowing the error budget, I can't say whether the additional error of the resistors is acceptable or not. The advantage of a programmable shunt is that I only have to stock one part for multiple designs. It is also easy to adjust the ADC span when you discover that you get the best performance by making it as big as possible.
