EMIF02-MIC06F3 is a highly integrated device designed to suppress EMI/RFI noise for dual microphone line filtering. The EMIF02-MIC06F3 Flip-Chip packaging means the package size is equal to the die size. That's why EMIF02-MIC06F3 is a very small device. Additionally, this filter includes an ESD protection circuitry which prevents damage to the application when subjected to ESD surges up to 15 kV.
