Hi,
I am trying to make a virtual ground with an opamp for battery cut off circuite to supply power to the mcu while switch cuttoff.
Attched is a scheme that describes the comoponents, i am not sure if all correct? also i am trying to figuer how to determine the R1 and R2_REF (maybee also to understand how this realy gives a virtual gnd), appreciate for anyone assitance?
In addtion, could also advice for a common opamp single ic?
Thanks in advance!
