ICS-40720

Ultra-Low Noise Microphone with Differential Output

APPLICATIONS

GENERAL DESCRIPTION

•

Smartphones

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.

Voice Control and Activation

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 sensitivity and

the same high SNR.
