QIf the reference input is an AC signal as stated below in figure1 and I still
would like a bipolar output, but I don't use the U2A OP2177, and float the R1A,
ground the RCOMA, then apply AC signal directly to VREFA. Is this connection
ok or it will cause any problem?
AI have attached a possible circuit. It is figure 19 on the datasheet but with
small changes. Keeping R1 and R2 connected will give a better performance in
the input signal.
I would like to highlight that the output will show the input signal inverted.
