The THS415x 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 THS415x 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.
