製品概要
概要
The MP34DTW01 is an ultra-compact, ultra-wide dynamic range, low-power MEMS microphone.
The MEMS microphone is capable of sensing both moderate and high sound pressure level of
acoustic signals, exhibiting the widest ever, and thus, sound dynamic range in the digital domain. The sensing element, capable of detecting acoustic waves, is manufactured using a specialized silicon micromachining process to produce audio sensors.
The MP34DTW01 interface is manufactured using a CMOS process that allows designing a dedicated circuit able to output a PDM digital signal.
The MP34DTW01 has an acoustic overload point of 140 dB SPL with a 60 dB signal-to-noise ratio. The MP34DTW01 is available in an SMD- compliant, EMI-shielded package and is guaranteed to operate over an extended temperature range from -40 °C to +85 °C
