Amps achieve max offset voltage of 20 μV at 25℃

摘要

The MAX4208/MAX4209H instrumentation amplifiers use a spread-spectrum autozeroing technique that constantly measures and corrects the input offset voltage, thereby eliminating drift over time and temperature. Both parts achieve an offset voltage of 20 μV max at 25℃, 30 μV max at 85℃, and 40 uV max at 125℃. The indirect current-feedback architecture offers true ground sensing and an input common-mode voltage range of -0.1 V to V_(DD) of -1.3 V.
