DESCRIPTION/ORDERING INFORMATION
The TPD2F702 is a two-channel EMI filter for audio interface applications. With the integration of 5000 pF
capacitor in a space saving low noise WCSP package, the TPD2F702 offers superior EMI noise supression
(2MHz to 6GHz) compared to discrete implementation. The device is optimized for AVIF connector or speaker
port interfaces. This low-pass filter array also provides system level ESD protection to eliminate the need for
external ESD clamps. The TPD2F702 exceeds ±30-kV ratings per IEC6100-4-2 Contact and Air-Gap
specifications. It is primarily used in the mobile-phone audio headphone speaker interface, but can be used in
other audio applications.
The TPD2F702 is a highly integrated device designed to suppress EMI/RFI noise in all systems subjected to
electromagnetic interferences. This filter includes ESD protection circuitry which prevents damage to the
application when subjected to ESD surges far exceeding IEC 61000-4-2 (Level 4).
The TPD2F702 is specified for –40°C to 85°C operation.
