Analogue MEMS Microphone - INMP401 / INMP404, InvenSense


InvenSense MEMS microphones with an analogue output, offer the next generation of microphone they have features such as high SNR (Signal to Noise Ratio), low current consumption, bottom port locations, wide frequency response ranges and supplied in compact package sizes. INMP401 and INMP404 both contain the MEMS microphone, an impedance converter and an output amplifier. They are ideal for near and far field applications and the omnidirectional MEMs analog microphones INMP401 and INMP404 are intended for a range of mobile applications where low power and high acoustic overload point (AOP) are important such as mobile devices, digital video cameras, Bluetooth headsets, video phones and teleconferencing systems.
