TDK InvenSense T583x Bottom Port Multi-Mode Microphones

TDK InvenSense T5837 and T5838 Bottom Port Microphones are multi-node low-noise digital microphones in a small package. These microphones consist of a MEMS microphone element and an impedance converter amplifier followed by a fifth order Σ-Δ modulator. A 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. These microphones feature a standard 3.5mm x 2.65mm x 0.98mm surface mount package and multiple modes of operation. TDK InvenSense T5837 and T5838 Bottom Port Microphones are suitable for various applications, including smartphones, microphone arrays, tablet computers, and cameras.
