The MP34DB02TR is a compact, high-performance, low-power, top-port digital MEMS (Micro-Electro-Mechanical Systems) microphone from the industry-leading semiconductor manufacturer, STMicroelectronics. This miniature audio sensor is designed to provide precise audio signal capture, making it an ideal solution for a wide range of applications that require reliable and clear sound input, such as mobile devices, smart home systems, and IoT (Internet of Things) devices.
Utilizing STMicroelectronics' advanced MEMS technology, the MP34DB02TR offers exceptional sound detection capabilities with an acoustic overload point of 120 dBSPL, ensuring high audio fidelity even in noisy environments. Its omnidirectional sensitivity pattern ensures consistent audio pickup from all directions, which is crucial for applications like voice recognition and teleconferencing.
The microphone operates within the frequency range of 20 Hz to 20 kHz, covering the full audible spectrum. It also features a high signal-to-noise ratio (SNR) of 63 dB, which minimizes background noise and enhances the clarity of the captured audio. This is particularly important in applications where clear voice capture is essential, such as in smartphones or voice-controlled devices.
The MP34DB02TR is designed with power efficiency in mind, drawing a low current consumption of just 0.6 mA in operation. This makes it an excellent choice for battery-powered devices where extending the battery life is critical. Additionally, its small footprint with a package size of 3 x 4 x 1 mm allows for easy integration into compact system designs without sacrificing performance.
Offered in a surface-mount package, the MP34DB02TR is also equipped with a PDM (Pulse Density Modulation) digital output, which provides a direct interface to digital processors without the need for an analog-to-digital converter. This simplifies the audio signal chain and reduces system complexity and cost.
Whether you're designing the next generation of smart assistants or enhancing the audio experience in portable devices, the MP34DB02TR from STMicroelectronics offers the perfect blend of performance, reliability, and efficiency.
