T5818 Bottom Port PDM Digital Output Multi-Mode Microphone GENERAL DESCRIPTION The T5818 is a multi-mode, low noise digital MEMS microphone in a small package. The T5818 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. The T5818 has multiple modes of operation: High Quality, Low-Power (AlwaysOn), and Sleep. The T5818 has high SNR in all operational modes. It has 135 dB SPL AOP in High Quality Mode and 120 dB SPL AOP in Low-Power mode. The T5818 is available in a standard 3.5 × 2.65 × 0.98 mm surface-mount package.
