MP45DT02 MEMS audio sensor omnidirectional digital microphone Datasheet - production data Description The MP45DT02 is a compact, low-power, top- port, omnidirectional, digital MEMS microphone. The MP45DT02 is built with a sensing element and an IC interface with stereo capability. The sensing element, capable of detecting acoustic waves, is manufactured using a specialized silicon micromachining process to produce audio sensors. The IC interface is manufactured using a CMOS process that allows designing a dedicated circuit able to provide a digital signal externally in PDM format. HLGA (4.72 x 3.76 mm) 6LD The MP45DT02 has an acoustic overload point of 120 dBSPL with a best on the market 61 dB Features signal-to-noise ratio and -26 dB sensitivity. Single supply voltage The MP45DT02 is available in an SMD-compliant Low power consumption metal (M) or plastic package and is guaranteed to 120 dBSPL acoustic overload point operate over an extended temperature range Omnidirectional sensitivity from -30 C to +85 C. PDM single-bit output with option for stereo The MP45DT02s digital output and package size configuration (1.25 mm thick) make this device the best HLGA package (SMD-compliant) plastic or solution for laptop and portable computing metal applications.
