Hi,
due to the limited PCI slots available in new mainboards (2) I had to change audio to use the onboard audio amplifier.
It obviously does not contain a mic preampflifier making an external amplifier necessary.
I simulated the circuit using LTSpice, but it displays db.
How can I change the simulation to display output voltage levels? Input voltage from the mic is 30mV/pp and I expect 750mV/pp as a minimum output voltage from the circuit.
