IM73A135V01 - dust and water resistant analog MEMS microphone

Description

The IM73A135V01 is designed for applications which require a microphone with high SNR (low self-noise), low distortion (high AOP), which is also IP57 robust to dust and water.

Best-in-class Signal to Noise Ratio (SNR) of 73dB(A) enables far field and low volume audio pick-up.

Features

  • Component level IP57 water and dust resistant.
  • Signal to noise ratio of 73dB(A) SNR.
  • Power optimized modes determined by VDD level.
  • Package dimensions: 4mm x 3mm x 1.2mm.
  • Acoustic overload point at 135dBSPL.
  • Differential output.
  • Flat frequency response with low frequency roll off.
  • Omnidirectional pickup pattern at 20Hz Typical.

IM73A135V01 IP57 dust and water resistant analog XENSIVTM MEMS microphone Description The IM73A135V01 is designed for applications which require a microphone with high SNR (low self-noise), low distortion (high AOP), which is also IP57 robust to dust and water. Best-in-class Signal to Noise Ratio (SNR) of 73dB(A) enables far field and low volume audio pick-up. The flat frequency response ( 20Hz low-frequency roll-off) and tight manufacturing tolerance improve the performance of multi-microphone array applications. The high performance analog microphone ASIC contains an extremely low noise preamplifier and a high performance differential output amplifier. Different power modes can be selected in order to suit specific current consumption requirements.
