This circuit (attached) is the output stage for a sensor control circuit. So far, it exists on paper, designed from a guide to single-supply circuits provided by TI. The purpose of P4 is to null out the baseline signal from the sensor. P5 allows a gain adjustment over an order of magnitude. The signal is pure DC.
My questions:
1. Will it work as I expect? I've done the math, but I may have missed something.
2. The parts count seems high.
3. Will the offset and gain adjustments interact? It would be nice if they didn't but it's not fatal.
Thanks in advance.
