SANICO A-MEMS MIC 2819 series is a front/rear type MEMS (micro-electromechanical systems) microphone with analog signal output. It provides high sensitivity, low power consumption and high SNR. Output impedance of this microphone is very low, it has much small affection from RF noise.
As MEMS type transducer and optimized ASIC are used inside this microphone, it has no thermal deterioration and superior thermal shock resistance. So, users can make full-automated assembly process with this microphone. This microphone has also very small and thin size in mechanical dimension, it is very suitable for portable devices with audio input function.
