Accurately measuring current flow is a standard requirement in several applications (Fig. 1). Depending on the specific need, the options available to designers can include discrete designs assembled ...

A current-sense amplifier (CSA) can be designed using a variety of topologies, two of which are shown in Figures 1 and 2. In the figure, an operational amplifier (op amp) is configured as a ...

When using a current sense amplifier, it is important to know how much error is present in the output so an accurate interpretation of the data can be obtained ...

Recently, an engineer asked for a solution to provide high-side monitoring of a 20-A load with an accurate overcurrent detection threshold of better than 5%. No easily accessible off-the-shelf ...
