Current Sense Amplifiers Analogue Output, Texas Instruments


Current and power measurement for real-time system protection, feedback control and high-accuracy system monitoring.

For these non-cancellable (NC), and non-returnable (NR) products, Terms and Conditions apply.



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.
