Hello friends,
I am working with a instrumentation amplifier to measure current.I am using MC1458 dual op amp.I am giving power supply from 7805 and 7905.outputs from these power supplies are not same (5.2v and -5.4v). so it affects the op amp gain.Is there any way to salve this problem?I have attached my circuit diagram
