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.
