Please note that any defect or non – conformance of this product must be discovered and reported to RS within 20 days of purchase.

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.
