Microphones

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.
