MMICT4076-00-908

Microphones Overview

The MMICT4076-00-908 is an analog MEMS microphone manufactured by TDK InvenSense. It features a rectangular surface-mount package measuring 2.75 mm in length, 1.85 mm in width, and 0.9 mm in depth. The device operates on a supply voltage of 1.8 V with a current consumption of 130 uA. Key electrical specifications include a sensitivity of -38 dB, a signal-to-noise ratio (SNR) of 63 dB, and an impedance of 250 Ohms. It supports a frequency range from 80 Hz to 20 kHz and functions within a temperature range of 0°C to +85°C.

Microphones Feature Summary

• Omnidirectional acoustic port located at the bottom of the package for flexible PCB placement.
• Integrated analog output interface compatible with standard audio processing circuits.
• Ultra-low power consumption design suitable for battery-operated portable devices.

Microphones Applications

• Mobile phones and smartphones
• Wearable electronic devices
• Smart home appliances

Microphones Procurement Notes

Verify the specific suffix -00-908 against official TDK InvenSense documentation to confirm packaging details such as reel or cut tape configuration. Ensure compatibility with RoHS standards and humidity sensitivity levels required for your assembly process. Cross-reference the manufacturer part number directly with authorized distributors to avoid counterfeit components.

Microphones Selection Notes

Select this component when an analog output is required rather than digital I2S interfaces found in other series like the ICS-43434. The low noise figure and compact form factor make it appropriate for space-constrained audio capture applications. Confirm that the system power supply aligns with the specified 1.8 V operating voltage.

Microphones Part Context
