Maybe there's a reason for that.
EDIT: why do I suggest an "old boring" Op Amp, instead of a "new exciting" one?
Well, it depends on goals.
If you already built a dozen Mic preamps and are bored stiff with them, ok, start plugging new chips in the old circuits.
Personally I'd try to design new circuits
, but hey, that's me
But as you seem to need a working Preamp to actually be used to make Music
, well, I'd try to avoid (unnecessary) surprises and build a robust well tried circuit.
Otherwise, you are walking a minefield.
As in: did you notice the MCP6022 is designed for PSUs of 2.5 to 5.5 V (single rail)?
With an absolute max rail of 7V?
Meaning that 9V battery would probably destroy it.
Not nice to find that after
you built it
Well spotted, thank you.
