MIC_SELECT
Microphone Select logic input control. The external microphone input is selected when
the MIC_SELECT signal (pin 1) is at Logic "1" (> 3.5 volts), and the internal microphone

2
VOUT
Amplifier output pin.
3
EXT_MIC_BIAS External microphone bias output.
4
V+
Positive supply pin.
5
INT_MIC−
Inverting internal microphone differential input. Can be operated as a single-ended input
by connecting a 0.22µF (or greater) capacitor between pin 6 and V−.
6
INT_MIC+
Non-inverting internal microphone differential input. Can be operated as a single-ended
input by connecting a 0.22µF (or greater) capacitor between pin 5 and V−.
7
V−
