... MAX9890 provides click-pop suppression even if the output blocking capacitors are already partially or fully charged. The MAX9890A features a 200ms switch turn-on time, enabling the use 100µF coupling capacitors at the output for applications requiring only a limited low- frequency response and a rapid turn-on time. The MAX9890B features a 330ms switch turn-on time, enabling the use of > ...

... The MAX9890’s internal switches connect the input to the output after the coupling capacitors are fully charged. The MAX9890A holds the switches open for 200ms and is ideal for coupling capacitors less than 100µF.
