Description
The MP34DT02 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 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.
The MP34DT02 has an acoustic overload point of
120 dBSPL with a 60 dB signal-to-noise ratio and
–26 dBFS sensitivity.
The MP34DT02 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.
Applications
• Mobile terminals
• Laptop and notebook computers
• Portable media players
• VoIP
