Bottom Port PDM Digital Output Multi-Mode Microphone
The ICS-51360 is a multi-mode, low noise digital MEMS
microphone in a small package. The ICS-51360 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 ICS-51360 has multiple modes of operation: Low-Power
(AlwaysOn), Standard and Sleep. The ICS-51360 has high SNR
in all operational modes. It has 130 dB SPL AOP in Standard
Mode and 120 dB SPL AOP in Low-Power mode.
The ICS-51360 is available in a standard 3.5 × 2.65 × 0.98 mm
surface-mount package. It is reflow solder compatible with
no sensitivity degradation.
