InvenSense Omni-Directional, Surface Mount Microphone Condenser -29 → -23dB

The Digital INMP521 MEMS microphone by InvenSense combines the MEMS element with CMOS technology. The ultra-low noise omnidirectional microphone has a PDM (Pulse Density Modulated) bottom port digital output which is ideal when you may require multiple microphones on a single data line.
The INMP521 has an extended wideband frequency response, high SNR and comes in a compact package, in addition to this it complies with the TIA-920 Telecommunications Telephone Terminal Equipment Transmission Requirements for Wideband Digital Wireline Telephones standard.
