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 theINMP401 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 6 Hz, 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 mm × 3.76 mm × 3.5 mm surface-mount package. It is reflow solder compatible with no sensitivity degradation.
