T5837 Bottom Port PDM Digital Output Multi-Mode Microphone GENERAL DESCRIPTION The T5837 is a multi-mode, low noise digital MEMS microphone in a small package. The T5837 consists of a MEMS microphone element and an impedance converter amplifier followed by a 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. The T5837 has multiple modes of operation: High Quality, Low-Power (AlwaysOn), Ultrasonic and Sleep modes. The T5837 has high SNR in all operational modes. It has 133 dB SPL AOP in High Quality Mode and 117 dB SPL AOP in Low-Power mode. The T5837 is available in a standard 3.5 × 2.65 × 0.98 mm surface-mount package.
