ICS-40730  
Ultra-Low Noise Microphone with Differential Output  
APPLICATIONS  
GENERAL DESCRIPTION  
Smart Home Devices  
The ICS-40730 is an ultra-low noise, differential analog  
output, bottom-ported MEMS microphone. The ICS-40730  
includes a MEMS microphone element, an impedance  
converter, a differential output amplifier and an enhanced RF  
package. The ICS-40730’s 74 dB SNR and ±2 dB sensitivity  
tolerance make it an excellent choice for microphone arrays  
and far field voice control applications.

FEATURES  
The ICS-40730 has a linear response up to 123 dB SPL with a  
differential output sensitivity specification of −32 dBV. It can  
be used in a single-ended mode with −38 dBV sensitivity and  
the same high SNR.
