MAX4208 Overview
These devices use a patented † spread-spectrum, autozeroing technique that constantly measures and corrects the input offset, eliminating drift over time and temperature and the effect of 1/f noise. This technique achieves less than 20µV offset voltage, allows groundsensing capability, provides ultra-low CMOS input bias current and increased mon-mode rejection performance. The MAX4208/MAX4209 provide high-impedance...
