Part Number:OPA2189
hello,
I looked at figure 43b of the OPA2189 Datasheet and was wonder if the input impedance of the plus terminal should be matched to the input of the minus terminal.
I need to invert 1 PPM 5 volt signals and was wondering if the inputs should be matched to terminate biases or that it's better to have the plus terminal grounded.
Awaiting responses
Tom
