e/Current sense amplifier

Information
has gloss	eng: Current sense amplifiers (also called current shunt amplifiers) are special purpose amplifiers that output a voltage proportional to the current flowing in a power rail. They utilize a "current-sense resistor" to convert the load current in the power rail to a small voltage, which is then amplified by the current-sense amplifiers. The currents in the power rail can be in the range of 1 A to 20 A, as a result, the current-sense resistor is a very low ohmic value resistor (usually in the range of a 1 mΩ to 100 mΩ). These amplifiers are designed to amplify a very small "sense voltage"—in the order of 10 mV to 100 mV in the presence of very large common-mode voltages—in the order of 5 V to 30 V). DC precision (low input offset voltage) and high common-mode rejection ratio (CMRR) are distinguishing characteristics of these amplifiers.
