Microphones are transducers that convert sound into an electrical signal for storage, transmission and/or rebroadcasting. Ranging from large boom style microphones to small and popular MEMS types, they are differentiated by impedance, voltage rating, sensitivity, frequency range, port location, overall size and mounting type. Analog, I2S, PDM and TDM output interfaces are available.

Learn how rectifiers convert AC to DC, compare half-wave and bridge circuits, and select voltage, current, recovery and thermal ratings for your design.
