Hello
I've hit a stumbling block with this A weighting circuit needing +/-15ac for powering the op amps.
No good to me with a portable 5v dc Arduino supply and not much 'headroom'.
I have found Single Supply Op Amps (SSM2135 @£5 a pop) I am wanting to use in place of the dual supply op amps shown.
Do you think it will work in it's current design?
What changes am I likely gonna have to make?
I will attach the OpAmp datasheets for reference.
Regards,
Mick
