Short description

The ICS-40300 is a low-noise, high SPL MEMS microphone with extended low frequency response. The ICS-40300 consists of a MEMS microphone element and an impedance converter amplifier. The ICS-40300 low frequency response makes it an excellent choice for applications requiring precise phase matching.

The ICS-40300 is pin compatible with the INMP401 and INMP411 microphones, providing an easy upgrade path. The ICS-40300 has a linear response up to 130 dB SPL. It offers low frequency extension down to 6Hz, resulting in excellent phase characteristics in the audio range. Low current consumption enables long battery life for portable applications. The ICS-40300 is available in a 4.72 Ã— 3.76 Ã— 3.5 mm surface-mount package. It is reflow solder compatible with no sensitivity degradation.
