The GMI4013S-2C30DB with Electret Condenser Microphone SMD RoHS from INGHAi is an ultra-low-noise, extremely small, digital-output micro electro-mechanical system (MEMS) microphone. It is designed for applications such as voice control, speech recognition, and audio recording in consumer, industrial, and automotive applications. The GMI4013S-2C30DB is RoHS compliant and features an omni-directional condenser microphone element encapsulated in a miniature 4-pin surface-mount device (SMD) package. Its thin 0.9mm profile allows it to fit in small and constrained spaces and its improved RF immunity makes it suitable for developing RF-immune products. It is constructed with back-port acoustic chamber and advanced integrated circuit design, deliver excellent acoustic performance with high sound pressure level (SPL) capability and low total harmonic distortion (THD). The GMI4013S-2C30DB can operate in continuous modes, providing audio signals with a low signal-to-noise ratio (SNR).
