PowerPAD is a trademark of Texas Instruments.
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.
