DMM-4026-B-I2S-R

Overview

The DMM-4026-B-I2S-R is a digital MEMS microphone manufactured by PUI Audio. It features an omnidirectional acoustic port and operates on a supply voltage range of 1.5 VDC to 3.6 VDC, with a typical nominal voltage of 1.8 VDC. The device delivers a sensitivity of -26 dB and maintains a frequency response from 20 Hz to 20 kHz. It utilizes an I2S digital output interface for data transmission. The component is constructed using silicon technology and is designed for surface mount installation.

Feature Summary

Integrates an I2S digital converter for direct interface with host processors
Provides consistent audio performance across the full frequency response range
Features an omnidirectional acoustic design for uniform sound capture

Applications

Consumer electronics audio input systems
Industrial control voice interfaces
Medical equipment communication modules

Procurement Notes

Verify the specific suffix configuration against the manufacturer's current datasheet to ensure compatibility with required I2S protocols. Confirm that the operating voltage aligns with the system's power rails within the specified 1.5 VDC to 3.6 VDC range. Check for RoHS compliance documentation if environmental regulations apply to the final assembly.

Selection Notes

Select this component when a digital output is required to eliminate analog noise susceptibility in noisy environments. The I2S interface simplifies digital signal processing integration compared to PCM/PDM alternatives. Ensure the application requires an omnidirectional pickup pattern and fits within the standard voltage constraints of low-power portable devices.

Part Context

This part belongs to the DMM series of digital MEMS microphones from PUI Audio. The series focuses on providing reliable audio solutions for various electronic applications. The DMM-4026-B-I2S-R specifically addresses needs for digital connectivity without requiring external analog-to-digital conversion stages.

Replacement Considerations

Direct substitutes include other PUI Audio models within the DMM series that share identical I2S output formats and physical dimensions. Verify pinout compatibility and electrical specifications before swapping with generic digital microphones.
