Hi,
I'm going to design an active low pass filter for the audio before feeding the signal into the PIC's analog pin. Sallen and key circuit is used.
I'm not sure what type of amplifier should I use. In the simulation, I just simply take one op amp in LTSpice to see the frequency response of the circuit.
Audio source: MP3 player, <3 Vpp
Is LMV716 suitable?
Or any amp is recommended for this application?
Thanks
