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

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.
