Hi All:
I am working with a design that uses the IVC102 but I need to add a null offset to the input to zero the detector offset out. The IVC102 does not have an input that I can use on that chip but the ACF2101 show that it has both the + and - input available on the chip but can use it? I noticed that the + input on the block diagram connects to the Sw Com. I have 7 individual detector channels that I want to connect to the ACF2101 individually but I want to adjust the offset for all of them with the same offset circuit. Does anyone know if you can use the plus input and leave the Sw Com open?
