Analog Devices has sold its MEMS Microphone product line to InvenSense. Please visit the InvenSense ADMP421 product page for all technical support and sales information. The ADMP421 is a low cost, low power, digital output bottom ported omni-directional MEMS microphone. The ADM421 consists of a MEMS microphone element, an output amplifier and a 4th order sigma delta modulator. The digital interface allows for the PDM (Pulse Density Modulated) 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 and a sleep mode enable long battery life for portable applications. The ADMP421 complies with the TIA-920 Telecommunications Telephone Terminal Equipment Transmission Requirements for Wideband Digital Wireline Telephones standard. The ADMP421 will be available in a very thin 3 mm × 4 mm × 1 mm surface mount package. It is reflow solder compatible with no sensitivity degradation. It is halide-free.
