1.6.1.10 IMP34DT05
The IMP34DT05
is an ultra-compact, low-power, omnidirectional, digital MEMS microphone 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 in PDM format.
The IMP34DT05 features low distortion with a 64 dB signal-to-noise ratio and -26 dBFS ±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.
