open-in-new Find other Fully differential amplifiers

Description

The THS412x is one in a family of fully differential-input, differential-output devices fabricated using Texas Instruments’ state-of-the-art submicron CMOS process.

The THS412x consists of a true fully-differential signal path from input to output. This results in excellent common-mode noise rejection and improved total harmonic distortion.
