KEY FEATURES

DESCRIPTION

Flip Chip construction

Bi-directional EMI/RFI low-pass

filter

ESD protection with integrated

line termination resistor

Bi-directional TVS protects

against negative ESD voltages

in audio applications

Proliferation of digital portable

LX7205 is an integrated low pass

electronic equipment has created a filter with ESD protection that filters

noisy environment in which all out the undesired frequencies as well as

devices become susceptible to protecting the port against both positive

Electromagnetic Interference (EMI). and negative ESD voltages. The device
