The THS2630 is one in a family of fully differential-input and differential-output devices fabricated using Texas Instruments state-of-the-art, high voltage, complementary bipolar process.

The THS2630 uses a true fully differential signal path from input to output, and has a high supply capability of up to ±17.5 V. This design leads to excellent common-mode noise rejection (95 dB at 800 kHz) and total harmonic distortion (−108 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 THS2630 is characterized for operation over the wide temperature range of –40°C to +85°C.
