ICS‐40638
High AOP Analog MEMS Microphone with Differential Output
GENERAL DESCRIPTION APPLICATIONS
The ICS‐40638 is an analog MEMS microphone with very high Automotive dynamic range and capable of operation up to 105°C. The ICS‐ Still and video cameras 40638 includes a MEMS microphone element, an impedance IoT devices converter, and a differential output amplifier. Other high‐performance specifications include 138 dB SPL acoustic overload point, tight ±1 dB sensitivity tolerance and enhanced immunity to both radiated and conducted RF interference.
FEATURES
The ICS‐40638 is available in a small 3.50 mm × 2.65 mm × 0.98 mm bottom port surface‐mount package.
SPEC PERFORMANCE
SNR
63 dBA
Current
