I want to use the PGA280 in an unusual way. From the schematic on the datasheet it appears I can input a signal on INP2/INN2 - close switches B1/B2 along with switches A1/A2 and whatever input on INP2/INN2 will appear on inputs INP1/INN1. I want to use INP1/INN1 as switched outputs to my load whilst being able to measure the signal with the load switched in or switched out. In this case the inputs are a differential current at low voltage +/-8 Volts max and +/- 1mA max. The load between INP1/INN1 is passive.
Is this possible?.
