This is a low-voltage, ultra-high-precision monitor featuring a Zero-Drift Instrumentation Amplifier (IA) that provides Rail-to-Rail inputs and outputs. Voltage gain is set by the feedback resistors. Accuracy of this circuit is set by the quality of resistors selected by the user, small-signal range is limited by VOL in single-supply operation. The voltage rating of this part restricts this solution to applications of<5.5V. This IA is sampled, so the output is discontinuous with input changes, thus only suited to very low frequency measurements. 2n3819 ir2125 l5973d moc3020 uc3842b amc7135 ds1821
