Description
The EMIF05-AUD02F3 chip is a highly integrated
audio filter device designed to suppress EMI/RFI
noise in all systems subjected to electromagnetic
interference.
This filter includes ESD protection circuitry, which
prevents damage to the protected device when
subjected to ESD surges up to 15 kV.
