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.

  • 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
  • KEY APPLICATIONS
    • Simple Single-Ended To Differential Conversion
    • Differential ADC Driver/Differential Antialiasing
    • Differential Transmitter And Receiver
    • Output Level Shifter
