The CMM-4030DT-26354-TR from CUI Devices is a digital MEMS microphone featuring an omnidirectional directivity pattern. This small package component is reflow solder compatible, making it suitable for automated assembly processes.
Key electrical specifications include a sensitivity range of -29 dB FS to -23 dB FS at 94 dB SPL and 1 kHz, a supply voltage range from 1.6V to 3.6V, and a current consumption of 0.54 mA. The microphone supports a frequency response from 100 Hz to 10,000 Hz, with a signal-to-noise ratio of 65 dBA and a total harmonic distortion of 0.2% at 94 dB SPL and 1 kHz. The acoustic overload point is rated at 120 dB SPL.
The digital interface utilizes 1-Bit PDM data format and operates with a clock frequency ranging from 1.0 MHz to 3.2 MHz. It has a low sleep current of 3-4 µA and features a quick wake-up time of 52 ms.
Mechanically, the microphone measures 4.00 x 3.00 x 1.00 mm and has a top-mounted acoustic port. It is designed for surface mount termination. The operating temperature range is -40°C to 105°C.
