Current Sense Amplifiers Analogue Output, Texas Instruments
Current and power measurement for real-time system protection, feedback control and high-accuracy system monitoring.
The Texas Instruments INA270 andINA271 family of voltage-output, current-sense amplifiers can sense drops across shunt resistors at common-mode voltages from –16 V to +80 V, independent of the supply voltage. The INA270 and INA271pinouts readily enable filtering.

Current Sensing Amplifiers have a voltage output that is proportional to the volt drop across a very low value resistor, usually in a high-current power rail. Hence they measure the current flowing in that power rail.
