    Introduction

    This is a high-performance, low-power, digital output omnidirectional MEMS microphone with a bottom port. The complete solution consists of a MEMS sensor, signal composition conditioning, an analog-to-digital converter, an anti-aliasing filter, power management, and an industry-standard 24-bit I2S interface. The I2S interface allows direct connection to digital processors such as DSPs and microcontrollers without the need for an audio codec in the system. With a high signal-to-noise ratio, this module is an excellent choice for near-field applications, featuring a flat, wideband frequency response that results in clear, natural sound.

    Features

  • High-precision 24-bit digital I2S interface
  • High signal-to-noise ratio of 61 dBA
  • High sensitivity of -26 dBFS
  • Stable frequency response from 60 Hz to 15 kHz
  • Low power consumption: low current consumption of 1.4 mA
  • High PSR: -75 dBFS

    • Specification

  • SCK: Serial data clock for the I2S interface
  • WS: Serial data word select for the I2S interface
  • L/R: Left/Right channel select.
             When set low, the microphone outputs a signal on the left channel of the I2S frame.
             When set high, the microphone outputs a signal on the right channel.
  • SD: Serial data output for the I2S interface.
  • VCC: Input power supply, 1.8V to 3.3V.
  • GND: Ground.
