Overview
The THS4131IDR is a high-performance, fully differential input/output amplifier manufactured by Texas Instruments. This device is part of the THS413x family, which is fabricated using Texas Instruments' state-of-the-art, high-voltage, complementary bipolar process. The THS4131IDR is designed to provide excellent common-mode noise rejection and low total harmonic distortion, making it suitable for high-voltage differential signal chains. Although the THS4131IDR itself is currently obsolete, an active replacement, THS413IDR, is available.
