Hi,
I am using a LMV321 OPAMP to amplify the difference between two audio signals, basically using it as a differential OPAMP. But I have powered up the OPAMP with a single supply. I do not have -ve supply available in my design.
When I bias the non-inverting input of the OPAMP with +Vcc/2, I get the same DC offset at the output of the OPAMP.
How do I get rid of this DC offset? decoupling caps at the OPAMP input and output do not help, nor does a high pass filter.
Thanks in Advance,
Surendra
