InvenSense’s digital MEMS microphones capitalize on this advantage by joining high-performance MEMS elements with state-of-the art wide dynamic range CMOS technology – a perfect combination. The first wave of digital microphones has used a PDM (Pulse Density Modulated) digital output. These microphones integrate the ADC, and output an undecimated 1-bit stream. PDM is an ideal interface to consider when you have a codec readily available and require multiple microphones, or have a substantial distance between the microphones and the codec. InvenSense is now leading the way toward the next family of digital microphones with fully decimated outputs capable of being connected directly into microcontrollers and DSPs. I²S output microphones, such as the ICS-43432 and the INMP441, are ideal when a codec is not needed. Featured Products T5919: Bottom Port PDM Digital Output Multi-Mode Microphone with Particle Ingress Filter (PIF) The T5919 is a multi-mode, low noise digital MEMS microphone in a small package. The T5919 consists of a MEMS microphone element and an impedance converter amplifier followed by a fourth-order Σ-Δ modulator. The digital interface allows the pulse density modulated (PDM) output of two microphones to be time multiplexed on a single data line using a single clock.
