SKR0600

Overview

The SKR0600 is a high-performance directional MEMS microphone offering analog output. It operates within a voltage range of 1.7 V to 3.6 V and covers a frequency response from 20 Hz to 20 kHz. The device features a noise cancellation capability of -32dB ±1dB and achieves a signal-to-noise ratio (SNR) of 67.5 dBA. This represents a 4 dB improvement over the previous SKR0400 series. Designed for surface mount installation, it serves as a low-noise alternative to traditional omnidirectional arrays.

Feature Summary

• Directional acoustic sensing architecture that inherently suppresses off-axis background noise
• High signal-to-noise ratio performance with industry-leading low noise characteristics
• Available in both analog and digital output configurations for flexible integration

Applications

• Smart speakers and internet-connected televisions
• Laptops and webcams for video conferencing
• Wearable devices and AR/VR headsets
• True wireless stereo (TWS) earbuds with active noise cancellation

Procurement Notes

Verify the specific output type required, as the SKR0600 series includes both analog and digital variants. Confirm the package suffix matches the desired configuration. Ensure the design-in process accounts for the 1.7 V to 3.6 V operating range. Consult official datasheets for precise mechanical dimensions and soldering profiles to ensure reliable surface mount assembly.

Selection Notes

Select the SKR0600 when superior voice isolation is critical without relying on complex software processing. Choose this component over omnidirectional microphones to reduce hardware complexity and power consumption. The 67.5 dBA SNR makes it suitable for noisy environments where clear voice capture is essential. Consider the analog or digital variant based on the host processor's interface capabilities.

Part Context

Soundskrit Inc., founded in 2019, specializes in bio-inspired MEMS technology derived from spider auditory research. The SKR0600 is part of their next-generation 0600 series, succeeding the SKR0400 model. This lineage represents a shift toward hardware-level noise suppression, aiming to replace large omnidirectional microphone arrays in consumer electronics with a single, highly directional component.
