Breakthrough Design: Sealed-Dual Membrane Transducer
The SDM MEMS architecture represents a significant shift in microphone design by sealing the air gaps inside a low-pressure chamber. This innovative approach minimizes one of the major sources of mechanical noise typically associated with backplate perforations and viscous damping.
Key benefits include:
- 130 dB SPL Acoustic Overload Point (AOP)
- 72 dB(A) Signal-to-Noise Ratio (SNR)
- Enhanced dynamic range for studio-quality voice capture
Advanced Read-Out ASIC with Power Scaling
The paired digital read-out ASIC introduces a current-feedback amplifier that is both power-efficient and reconfigurable. Users can dynamically scale power consumption based on SNR needs, providing flexibility for both battery-sensitive and performance-critical applications.
This results in:
- Optimized performance-to-power ratio
- Reconfigurable modulator for adaptable SNR vs power trade-off
- Integration-ready design for compact IoT, mobile, or edge AI devices
