STMicroelectronics MP45DT02TR

The STMicroelectronics MP45DT02TR is a compact and high-performance digital MEMS (micro-electro-mechanical systems) microphone that is designed to operate at low power consumption. It uses an advanced acoustic sensor technology that is based on the capacitive principle, which enables it to detect sound waves and convert them into electrical signals. The device is equipped with an integrated preamplifier and an A/D converter that enables it to deliver high-quality digital audio output. It is also designed with a fixed-linearity algorithm that provides a linear response to sound pressure levels (SPLs) ranging from 30 dB to over 120 dB.

The MP45DT02TR digital microphone is housed in a tiny 3.76 x 4.72 x 1.25 mm package making it suitable for use in a wide range of portable devices such as smartphones, tablets, and other similar consumer applications. It is also designed with advanced power management features that enable it to operate at low power consumption making it ideal for battery-powered devices. Additionally, the device operates on a wide supply voltage range of 1.6 V to 3.6 V, making it suitable for use in a variety of applications
