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.

The ICS‐40720 is available in a small 4.00 mm × 3.00 mm ×

1.20 mm surface‐mount package.
