Other Parts Discussed in Thread: INA159
The INA159 has a supply voltage range of +1.8V to +5.5V with an input voltage range of up to +17.5V. Does this mean that the amp could be powered by +5V and could be fed, say, a +12V input signal? The fixed gain of 0.2 would yield a +2.4V output, well within the supply range, but it seems unusual for the input of an IA to exceed the supply, especially by so much.
