EV_ICS-40638-FX
Evaluation version of the ICS-40638
Note: The ICS-40638 and ICS-40638 EVB are marked as EOL and are not recommended for new designs.
EV_ICS-40638-FX – Evaluation Board
Simple evaluation board which allows for quick evaluation of the ICS-40638 analog MEMS microphone. The small size and low profile of the flexible PCB enables direct placement of the microphone into a prototype or an existing design for an in situ evaluation. The evaluation board consists of a bottom port microphone soldered to a flexible PCB with color-coded wires attached. The only other component on the board is a 0.1μF supply bypass capacitor.
Please refer to the App Note below “AN-000048 – PDM Digital Output MEMS Microphone Flex Evaluation Board User Guide” for more detailed information.
ICS-40638
The ICS-40638 is an analog MEMS microphone with very high dynamic range and capable of operation up to 105°C. The ICS-40638 includes a MEMS microphone element, an impedance 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.
The ICS-40638 is available in a small 3.50 mm × 2.65 mm × 0.98 mm bottom port surface-mount package.
SmartSound™ analog MEMS microphones
Discover the analog advantage with pure, natural audio capture
Our analog microphones deliver clean, natural sound with the low noise and high sensitivity that audio engineers trust. Unlike digital microphones- which include onboard converters and are optimized for plug-and-play system integration-analog microphones provide a direct, uncompressed audio signal path.
