The THS4130 and THS4131 devices (THS413x) are a family of fully differential input/output amplifiers fabricated using Texas Instruments state-of-the-art, high-voltage, complementary, bipolar process.

The THS413x use a true, fully differential signal path from input to output, and provide a high supply capability of up to ±15 V. This design leads to an excellent common-mode noise rejection performance (95 dB at 800 kHz) and total harmonic distortion (−102 dBc at 2 V PP, 250 kHz). The wide supply range allows high-voltage differential signal chains to benefit from the improved headroom and dynamic range without adding separate amplifiers for each polarity of the differential signal.

The THS413x are characterized for operation over the wide temperature range of –40°C to +85°C.
