EMIF02-MIC06F3 2-line IPAD™ EMI filter and ESD protection Datasheet - production data Description The 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. Lead -free Flip-chip package (8 bumps) Additionally, this filter includes an ESD protection circuitry which prevents damage to the application when subjected to ESD surges up to 15 kV. Features Figure 1.

Configuration ECI A2 GND GND Mic Bias A3 C11 B1 GND C21 R11 R31 R21 B3 Mic2p to ASIC Mic2n R22 C1 C12 GND GND C3 R12 GND C22 GND B2 and C2 are ground pins ECI pin connection The ECI pin (enhancement control interface) is an input pin for the audio pre-amplifier chip which detects the voltage of the microphone line MIC2P in case the user presses the onhook/off-hook button on the headset. When the user selects off-hook using the headset button, the MIC2P is shorted to MIC2N which is grounded. If your design does not support the ECI feature, the ECI pin must be left open (not connected). Table 1.
