IMP34DT05 MEMS Audio Sensor Omnidirectional Digital Microphone
IMP34DT05 MEMS Audio Sensor Omnidirectional Digital Microphone
STMicroelectronics' IMP34DT05 MEMS omnidirectional digital microphone for industrial applications
STMicroelectronics' IMP34DT05 is an ultra-compact, low-power, omnidirectional, digital MEMS microphone built with a capacitive sensing element and an IC interface. The sensing element, capable of detecting acoustic waves, is manufactured using a specialized silicon micromachining process dedicated to producing 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. The IMP34DT05 is a low-distortion digital microphone with a 64 dB signal-to-noise ratio and -26 dB FS (full signal) ±3 dB sensitivity. The IMP34DT05 is available in a top-port, SMD-compliant, EMI-shielded package and is guaranteed to operate over an extended temperature range from -40°C to +85°C.
