I am trying to amplify the difference between VQ5_N and VQ5_P.
VQ5_N measures 2.125V
VQ5_P measures 2.435
I have set the Gain resistors R1 & R2 to produce a Gain = 10, so I would expect to see VQ5_FILT (the output) to be (2.435 - 2.125) * 10 or roughly 3.1V. However, Pin 4 (Vo) always measures 0.009V. This is true even if I remove the Anti-Aliasing Filter (R138 & C10).
I have confirmed that Vref = Ground, ENABLE 4.25, and VCC = 4.25V
Do you have advice on my my output is always stuck at ~0V?
