Overview

The MP34DT05TR-A is an ultra-compact, low-power, omnidirectional digital MEMS microphone with a capacitive sensing element and an IC interface. It provides a Pulse Density Modulation (PDM) output and features a top-port design suitable for slim electronic devices.

Why Choose This Part

This microphone is built with a sensing element capable of detecting acoustic waves and is manufactured using a specialized silicon micromachining process. It offers a wide supply voltage range of 1.6V to 3.6V and features a standby mode that drops current consumption to just 5uA, extending battery life in mobile designs.

Applications

Speech Recognition Interfaces
High signal-to-noise ratio and flat frequency response make it ideal for voice-activated smart home assistants.
Portable Consumer Electronics
Low profile 1.0mm height and 0.65mA typical current draw suit laptops, tablets, and wearable media players.
Acoustic Anti-theft Systems
Reliable sound sensing for security monitoring and glass-breakage detection in industrial or residential environments.
VoIP Equipment
Integrated EMI shielding ensures clear audio transmission in wireless communication hardware.

Getting Started

To evaluate this sensor, engineers can use the X-NUCLEO-CCA02M2 expansion board which interfaces with STM32 Nucleo development boards. Ensure PDM-to-PCM conversion is handled in your firmware, typically using the STM32 Open.Audio library or a dedicated hardware decimation filter.
