key applications

description

The THS414x is one in a family of fully differential

input/differential output devices fabricated using

Texas

Instruments’

state-of-the-art

BiComI

complementary bipolar process.

The THS414x is made of a true fully-differential

signal path from input to output. This design leads

to an excellent common-mode noise rejection and

improved total harmonic distortion.
