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 d B SNR and ±2 d B 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 d B SPL with a differential output sensitivity specification of - 32 d BV. It can be used in a single‐ended mode with - 38 d BV 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.
