PIN DESCRIPTIONS PIN NAME DESCRIPTION 1 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 inputs are selected by applying Logic "0" to the pin (< 1.5V). 2VOUT Amplifier output pin. 3 EXT_MIC_BIAS External microphone bias output. 4 V+ Positive supply pin. 5INT_MIC − Inverting internal microphone differential input. Can be operated as a single-ended input by connecting a 0.22 µF (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 0.22 µF (or greater) capacitor between pin 5 and V−. 7V − Negative supply pin. 8 EXT_MIC_IN External microphone signal input.
