STMicroelectronics MP34DT04TR Digital MEMS Microphone

The MP34DT04TR is a high-quality, compact, low-power, omnidirectional digital MEMS (Micro-Electro-Mechanical Systems) microphone from STMicroelectronics. This cutting-edge audio sensor is designed to deliver crystal clear sound capture, making it an ideal choice for a wide range of applications, including mobile devices, smart home systems, and IoT (Internet of Things) devices.

Featuring a sensitivity of -26 dBFS and an acoustic overload point of 120 dBSPL, the MP34DT04TR ensures excellent audio performance even in noisy environments. Its signal-to-noise ratio (SNR) of 61 dB and wide frequency response from 20 Hz to 20 kHz enable the microphone to accurately capture a full range of sounds, from subtle whispers to loud music, without loss of fidelity.

The MP34DT04TR operates on a supply voltage between 1.64 V and 3.6 V, which allows for seamless integration with most modern electronic devices. Additionally, its low power consumption is a significant advantage for battery-powered applications, ensuring longer operation times between charges.

Engineered with a top-port design, the MP34DT04TR comes in a compact 3 x 4 x 1 mm LGA package that is easy to integrate into space-constrained designs. Its robust construction is complemented by an extended temperature range of -40°C to +85°C, making it suitable for use in a variety of environmental conditions.

One of the standout features of the MP34DT04TR is its PDM (Pulse Density Modulation) digital output, which provides a direct interface to external processors and eliminates the need for an audio codec in the system. This simplifies the design and reduces the number of external components required, saving both space and cost.

In summary, the MP34DT04TR from STMicroelectronics is a versatile and powerful digital MEMS microphone that offers top-notch audio capture capabilities. Its small size, low power consumption, and high performance make it an excellent choice for designers looking to incorporate high-quality sound recording into their products.
