Note 7. The voltage difference between MICP and MICN pins. AC coupling capacitor should be inserted in series at each
input pin. Full-differential mic input is not available at MGAIN3-0 bits = “1000” or “0000”. Maximum input
voltage of MICP and MICN pins are proportional to AVDD voltage, respectively.
