The MP34AB01HTR from STMicroelectronics is a state-of-the-art, high-performance MEMS (Micro-Electro-Mechanical Systems) audio sensor that is a testament to the company's commitment to providing advanced acoustic solutions. This microphone is part of STMicroelectronics' extensive portfolio of MEMS microphones which are designed to deliver exceptional sound quality for a wide range of applications.
With its compact and sensitive design, the MP34AB01HTR is capable of capturing high-quality audio with excellent fidelity. It features an omnidirectional sensitivity pattern which makes it ideal for picking up sound from any direction, ensuring that audio input is consistent and reliable. This microphone is also equipped with an acoustic overload point of 120 dBSPL, allowing it to perform well in environments with high sound pressure levels without compromising audio quality.
The MP34AB01HTR operates within a frequency range of 20 Hz to 20 kHz, which covers the full audible spectrum, ensuring that both low and high frequencies are accurately reproduced. It also boasts an impressive Signal-to-Noise Ratio (SNR) of 63 dB, which means that the microphone can pick up the intended audio signals even in noisy environments.
This MEMS microphone is designed with a sensitivity of -38 dBV/Pa and has a low power consumption, making it suitable for battery-powered devices where energy efficiency is crucial. Its digital output is provided via an I²S (Inter-IC Sound) interface, which allows for easy integration with other digital systems and ensures a clean, noise-free signal transmission.
The MP34AB01HTR is encapsulated in a tiny 3x4x1 mm HCLGA (Heterogeneous Composite Land Grid Array) package that is not only space-saving but also offers enhanced shock resistance and reduced sensitivity to mechanical vibrations. This makes it an excellent choice for portable electronic devices, such as smartphones, tablets, and laptops, as well as for smart home devices, including smart speakers and voice-controlled systems.
Overall, the MP34AB01HTR MEMS microphone is a versatile and reliable component that offers superior acoustic performance for a multitude of audio recording and voice capture applications.
