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.
