Part Number:OPA2132
Can you explain to me why with this type of schema, programmable via the ADG441 a gain of 1 or a gain of -1. We need to change the OPA2132U IC92 after a
few months of use due to off-specification output offset> 0.5μV

On the IC92-7 pin we have a difference of 0.20145-0.19721 = 4.24mV totally abnormal compared to the amp specification which gives a max offset of ± 0.5mV
