Fully Differential Input/Output Low Noise Amplifier - THS4131

THS4131 (ACTIVE)

Fully Differential Input/Output Low Noise Amplifier

Recommended alternative parts

  • THS4521  -  1.14mA/ch, 145MHz fully diff amp

Description

The THS413x 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 THS413x 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.

  • Low Noise
    • 1.3 nV/√Hz Input-Referred Noise
  • Differential-Input/Differential-Output
    • Balanced Outputs Reject Common-Mode Noise
    • Reduced Second-Harmonic Distortion Due to Differential Output
