Datasheet Summary
ICS‐40720
Ultra‐Low Noise Microphone with Differential Output
GENERAL DESCRIPTION
The ICS‐40720 is an ultra‐low noise, differential analog output, bottom‐ported MEMS microphone. The ICS‐40720 includes a MEMS microphone element, an impedance converter, a differential output amplifier and an enhanced RF package. The ICS‐40720’s 70 dB SNR and ±2 dB sensitivity tolerance make it an excellent choice for microphone arrays and far field voice control applications. The ICS‐40720 has a linear response up to 124 dB SPL with a differential output sensitivity specification of - 32 dBV. It can be used in a single‐ended mode with - 38 dBV sensi vity and the same high SNR. ...
