Description

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
