SKR0410

Overview

The SKR0410 is a digital directional MEMS microphone featuring a Pulse-Density Modulation (PDM) output interface. It operates within a voltage range of 1.7 V to 3.6 V and covers an audio frequency response from 20 Hz to 20 kHz. The device provides a signal-to-noise ratio of 63.5 dBA and includes noise cancelling capabilities rated at -23dB ±1dB @ 94dB SPL. Designed as a surface-mount component, it utilizes a dipole polar pattern to isolate user voice while reducing background noise and reverberation.

Feature Summary

• Directional acoustic pickup using a dipole polar pattern for superior voice isolation
• Digital PDM output interface eliminating the need for analog-to-digital conversion
• Integrated noise cancellation hardware reducing reliance on complex signal processing

Applications

• Laptops and notebooks requiring high-fidelity voice capture
• Webcams and video conferencing systems
• Smart speakers and internet-connected televisions
• True wireless stereo (TWS) earbuds and headsets

Procurement Notes

Verify the specific ordering suffix to confirm package type and tape/reel specifications. Ensure compatibility with host processor PDM interfaces regarding clock rates and data alignment. Confirm supply chain availability through authorized distributors as lead times may vary by region.

Selection Notes

Select this model when digital output is preferred over analog to simplify system design. Consider its low power consumption and small form factor for space-constrained portable devices. Evaluate the dipole pattern suitability against omnidirectional alternatives based on environmental noise requirements.

Part Context

The SKR0410 represents Soundskrit's transition into digital MEMS technology, following the analog SKR0400 series. It serves as a direct successor in functionality but offers digital integration benefits. This component addresses the industry shift toward software-defined audio processing by providing clean, directional input directly to digital hosts.

Replacement Considerations

No public confirmed substitute part numbers are available. The SKR0410 utilizes proprietary directional MEMS architecture that differs significantly from standard omnidirectional competitors.
