Hi,
I've been having a bit of trouble finding a summer IC that can perform the following calculation:
V0 = V1 + V2 - (V3 + V4)
I found the LM324 which includes that calculation in its documentation, but it requires V1 + V2 > V3 + V4 since it's only got V+ and GND inputs. This requirement is a deal-breaker since my possible V0 can be either positive or negative.
In my circuit, V1-4 all can range from 0 to 100 mV. Does anyone know of a specific IC that would be able to meet these criteria?
Thanks for the help,
-Ben
