The ICS-40740 is an ultra-low noise, high dynamic range, differential analog output, bottom-ported MEMS microphone. The ICS-40740 includes a MEMS microphone element, an impedance converter, a differential output amplifier and an enhanced RF package. The ICS-40740’s 70 dB SNR and ±1 dB sensitivity tolerance make it an excellent choice for microphone arrays and far field voice control applications.

The ICS-40740 has a linear response up to 132.5 dB SPL with a differential output sensitivity specification of −37.5 dBV.

The ICS-40740 is available in a small 4.00 mm × 3.00 mm × 1.20 mm surface-mount package.
