SPM0102ND3-2

Overview

The Syntiant SPM0102ND3-2 is a mini, low-power, bottom-port silicon digital microphone featuring a single-bit PDM output. It operates within a voltage range of 1.5 V to 5.5 V and provides an omnidirectional frequency response from 100 Hz to 8 kHz. The device exhibits a sensitivity of -42 dB ±4 dB at 94 dB SPL, designed for efficient audio capture in edge AI applications.

Feature Summary

• Bottom-port MEMS architecture for compact integration
• Single-bit PDM digital output interface
• Omnidirectional acoustic pickup pattern

Applications

• Edge AI voice recognition systems
• Battery-powered consumer electronics
• Always-on audio sensing devices

Procurement Notes

Verify the specific suffix (ND3-2) against official Syntiant documentation to confirm pinout and packaging details. Ensure compatibility with your system's PDM interface timing requirements. Confirm operating voltage ranges align with your power supply design before procurement.

Selection Notes

Select this component when a low-profile, digital microphone is required for space-constrained designs. The bottom-port configuration facilitates surface mounting without obstructing top-side components. Verify that the host processor supports the required PDM data rate and clock frequencies for proper signal acquisition.

Part Context

Syntiant specializes in neural decision processors and intelligent sensing solutions for edge AI. This microphone complements their hardware ecosystem by providing high-quality audio input for always-on listening applications, enabling local processing without cloud dependency.

Replacement Considerations

Consult official Syntiant documentation for verified substitute part numbers. Do not assume functional equivalence with generic MEMS microphones due to specific PDM interface and sensitivity requirements.
