Stereo Microphone Module I2S

 
MSM26S4030H0 is a versatile, sub-port, MEMS microphone chip with I2S digital output. I2S is a general-purpose digital audio interface and is widely used in DSP and digital audio processing. In a traditional audio system, the audio signal collected by the microphone will be converted to analog voltage and output and then processed by the main controller chip after being converted to digital signal and encoded through the codec's ADC. However, the product of MSM261S4030H0 series has built-in 24bit I2S audio port, so it can realize full digital signal connections with DSP or MCU without adding extra Codec. The raw digital audio signal is sent directly to the main controller chip. As a result, the complexity of designing signal chains will be greatly reduced, making the product have advantages in terms of size, cost, power consumption and anti-interference.
 
Nowadays, personal portable electronics products are becoming increasingly dominant in the consumer market. This type of silicon-made microphone learns the advantages of semiconductor technology and combines high manufacturing repeatability, excellent audio performance and excellent expandability. Therefore, it can be safely said that in the near future the traditional ECM (electret condenser microphone) will be replaced by low-cost and high-performance MEMS.
