SPM0103NE3-2

Overview

The SPM0103NE3-2 is a digital MEMS microphone manufactured by Infineon Technologies (formerlyams AG). It features an I2S digital interface for audio data transmission. The device includes an integrated ASIC for signal conditioning and analog-to-digital conversion. It operates with a supply voltage range of 1.59 V to 3.63 V. Key electrical parameters include a sensitivity of -26 dBFS (referenced to 1 Pa/0 dB = 1 V/Pa) at 1 kHz, a signal-to-noise ratio (SNR) of 64 dBA, and a total harmonic distortion (THD) of less than 0.5% at 1 kHz with a sound pressure level of 94 dB SPL. The component is housed in a compact 1.87 mm x 1.43 mm x 0.65 mm package.

Feature Summary

Digital I2S output interface eliminates the need for external analog-to-digital converters.
Integrated ASIC provides high signal integrity and low noise performance.
Compact surface-mount design suitable for space-constrained mobile devices.

Applications

Smartphones and tablets for voice capture and hands-free communication.
Voice-controlled smart home assistants and IoT devices.
Laptops and ultrabooks for conferencing and voice recognition.

Procurement Notes

Verify the specific suffix and tape-and-reel quantity against the manufacturer's latest datasheet before ordering. Confirm that the I2S clocking requirements match your system controller. Ensure ESD protection measures are adequate during handling, as MEMS structures are sensitive to electrostatic discharge. Cross-reference the part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a digital output is required to simplify PCB layout and reduce analog noise susceptibility. Compare sensitivity and SNR specifications against other MEMS microphones if higher acoustic performance is needed. Consider the physical dimensions and mounting orientation constraints of the target enclosure. Verify compatibility with the host processor's I2S interface timing and word select configurations.

Part Context

This microphone belongs to the SPH series of digital MEMS microphones from Infineon. These devices are designed for high-volume consumer electronics applications requiring reliable voice input. The series typically offers various directivity patterns and package sizes to accommodate different form factors in portable devices.

FAQ

What is the default I2S format supported by the SPM0103NE3-2?

The device supports standard I2S digital audio format with left-justified or right-justified options configurable via hardware pins, typically defaulting to a standard alignment.
