Note: The ICS-40638 and ICS-40638 EVB are marked as EOL and are not recommended for new designs.
EV_ICS-40638-FX β 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 0.1ΞΌF supply bypass capacitor.
Please refer to the App Note below βAN-000048 β PDM Digital Output MEMS Microphone Flex Evaluation Board User Guideβ 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 105Β°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 Β±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 Γ 2.65 mm Γ 0.98 mm bottom port surface-mount package.
