ICS-40300

P1-P3P4-P6P7-P9P10-P12P13-P15P16-P16
ICS-40300
High SPL Analog Microphone with Extended Low Frequency Response
GENERAL 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 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.
*Protected by U.S. Patents 7,449,356; 7,825,484; 7,885,423; and 7,961,897.
Other patents are pending.
