Omnidirectional Microphone With Bottom Port And Digital Output

The ADMP421 is a low cost, low power, digital output bottom ported omnidirectional MEMS Microphone The ADMP421 consists of a MEMS Microphone element, an output Amplifier and a fourth-order - Modulator The digital Interface allows for the pulse density modulated (PDM) output of two Microphones to be time multiplexed on a single data line using a single Clock The ADMP421 has a high SNR and a high sensitivity, making it an excellent choice for far field applications. The ADMP421 has a flat wideband frequency response resulting in natural sound with high intelligibility. Low current consumption enables long battery life for portable applications. A built-in particle Filter provides for high reliability. By Analog Devices, Inc.
