Fully Differential Input/Output Low Noise Amplifier

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.
