open-in-new Find other Fully differential amplifiers

The THS413x device 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 THS413x 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.
