I have a project where I am trying to get audio from an Android headset accessory into a teensy audio board line in using the LMV358 op Amp breakout board.
I am not able to get any signal from the LMV358, only a floating voltage at around 2.5v.
I am using this information for the arduino spec to wire it: https://source.android.com/devices/acce ... adset-spec
Essentially, I am wiring the mic out to the input of the LMV358, and plugging the output of the LMV358 straight to the line in of the teensy audio board.
My question is: do I need additional circuit components? Are my assumptions correct that this setup should work?
