SmartSound™ Analog MicrophonesLike all InvenSense MEMS microphones, the analog output portfolio leverages unique high-performance MEMS elements. Analog output is still a common audio interface type, and has been used by electret microphones for decades. InvenSense MEMS microphones offer significant performance improvements to this old standard. They have similar or better SNR in smaller size, provide consistent performance part-to-part and over temperature, and offer a wider dynamic range. |

| Features / Benefits | The ICS‐40212 has a very high dynamic range and a low‐power AlwaysOn mode with power consumption as low as 55 uA. | The ICS-40214 is an analog MEMS microphone with very high dynamic range and single ended output. | The ICS-40216’s 65.5 dB SNR and ±1 dB sensitivity tolerance plus wide dynamic range make it an excellent choice for microphone arrays and far field voice control applications. | The ICS-40300 is a low-noise, high SPL MEMS microphone with extended low frequency response that makes it an excellent choice for applications requiring precise phase matching. | The ICS-40638 has a high dynamic range and very high AOP which enables clear audio capture in loud conditions: wind, concerts, close range speaking, etc. It is capable of operation up to 105°C. | The ICS-40720 is an ultra-low noise, differential analog microphone. The 70 dB SNR and ±2 dB sensitivity tolerance make it an excellent choice for microphone arrays and far field voice control applications. | The ultra-low noise ICS-40730 with its 74 dB SNR and ±2 dB sensitivity tolerance make it an excellent choice for microphone arrays and far field voice control applications. The 20 Hz low frequency roll off enables enhanced low frequency ANC. | The two sound ports located on the bottom and top of the ICS-40800 package allows the microphone to exhibit variable sensitivity to sound based on angle of arrival. Low current draw provides long life for battery operated devices. |
