FAQs

Our MEMS MICs are designed with ultra-low power consumption. The typical power consumption ranges from 120μw milliwatts to 170μw milliwatts, depending on the specific model and operating conditions. This allows for extended battery life in various applications such as smartphones, wearables, and IoT devices.

Yes, our MEMS MICs are engineered to be highly durable. They can operate within a wide temperature range from -40℃ to 100℃. Additionally, they have excellent resistance to humidity and vibration, making them suitable for use in industrial, automotive, and outdoor applications where environmental factors can be challenging.

Our MEMS MICs feature a compact design. They are significantly smaller than traditional microphones. The typical dimensions are 2.75mm x1.85mm x0.90mm, which enables easy integration into space-constrained devices like smartwatches, earbuds, and miniature audio recorders without sacrificing performance.

 It enables real-time airflow adjustments, reducing lag and optimizing vapor consistency for a smoother user experience.

Yes, it supports integration with major IoT ecosystems for smart diagnostics and remote control.

A MEMS (micro-electro-mechanical system) sensor combines microscopic mechanical structures with integrated electronics to measure physical phenomena such as pressure, acceleration, or sound Wikipedia. The sensing element typically forms a tiny variable capacitor whose capacitance changes under applied force; this variation is converted into an electrical signal that’s conditioned and digitized by on-chip circuitry Analog Devices.

Key selection criteria include signal-to-noise ratio (SNR), frequency response (20 Hz–20 kHz for human voice), acoustic overload point (AOP), and output interface (analog vs. PDM) e2e.ti.comsameskydevices.com. For digital voice applications—especially with XMOS processors—opt for a PDM MEMS microphone with an SNR ≥ 67 dB and an AOP ≥ 120 dB to ensure clear far-field voice pickup and noise resilience XMOS - Bringing technology to life.

XMOS voice processors like the XVF3610 provide dedicated PDM interfaces: connect standard PDM MEMS microphones to the MIC_DATA pins at a 3.072 MHz clock rate, assigning left/right channels on alternate clock edges XMOS - Bringing technology to life. The processor’s decimation filters convert the high-rate PDM stream into 16 kHz PCM audio for far-field voice processing, ensuring low distortion (THD+N ≤ –110 dB) and a wide dynamic range (≥ 140 dB) XMOS - Bringing technology to life.

Mechanical shock and stiction (surface sticking) are leading causes of MEMS sensor drift or breakage; even minor impacts can degrade calibration Symmetry ElectronicsEDN. Protect devices with shock-absorbent packaging, control ESD via proper grounding, and implement clean-room assembly to avoid micro-contamination that can cause stiction EDN. Regular recalibration and environmental sealing further preserve long-term accuracy.

Typical symptoms include response-time lag, zero-offset drift, or reduced accuracy. First, verify power-supply stability and filter out electrical noise WFSensors. Check for mechanical misalignment or diaphragm damage by inspecting sensor packaging. If drift persists, perform a factory calibration routine or replace the device if it exhibits permanent offset shift WFSensors.
