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.
FeaturesWhen 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.
