www.ti.com THS4120 THS4121 SLOS319D – FEBRUARY 2001 – REVISED OCTOBER 2004 HIGH-SPEED FULLY DIFFERENTIAL I/O AMPLIFIERS FEATURES High Performance – 100 MHz, –3 dB Bandwidth – 50 V/µs Slew Rate – 75 dB Total Harmonic Distortion at 1 MHz (VO = 2 VPP) – 5.4 nV/√Hz Input-Referred Noise (10 kHz) Differential Input/Differential Output – Balanced Outputs Reject Common-Mode Noise – Differential Reduced Second Harmonic Distortion Power Supply Range – VDD = 3.3 V 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.
