DescriptionSTMicroelectronics IMP34DT05 MEMS omnidirectional digital microphone for industrial applications
OverviewSTMicroelectronics' 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.
Key FeaturesLow power consumption AOP = 122.5 dB SPL (sound pressure level) 64 dB signal-to-noise ratio Omnidirectional sensitivity -26 dB FS ±3 dB sensitivity HCLGA package: top-port design, SMD-compliant 10-year longevity Low distortion High SNR Enhanced ESD protection Omnidirectional sensitivity Standard package form factor
ApplicationsAnti-tampering devices Vibration monitoring Audio-activated functions Predictive maintenance Noise cancelling Sound detection for alarm systems Human/machine voice interface Anti-theft systems
