emif02-mic01f2

Manufacturer Part Number
emif02-mic01f2
Description
2-line Ipad, Emi Filter Including Esd Protection
Manufacturer
STMicroelectronics
Datasheet
IPAD™
Main application
Description
The EMIF02-MIC01F2 is a highly integrated
device designed to suppress EMI / RFI noise for
microphone line filtering.
The EMIF02-MIC01F2 Flip-chip packaging
means the package size is equal to the die size.
This is why the EMIF02-MIC01F2 is a very small
device.
Additionally, the filter includes an ESD protection
circuit to prevent the protected device from
destruction when subjected to ESD surges up
to 15 kV.
Benefits
Complies with the standards:
IEC 61000-4-2
on input and output pins
