THS4131CDR General Description

The THS413x device is one in a family of fully-differential input/differential output devices fabricated using Texas Instruments state-of-the-art high voltage complementary bipolar process.

The THS413x is made of a true fully-differential signal path from input to output and 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 its improved headroom and dynamic range without adding separate amplifiers for each polarity of the differential signal.

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