An op amp-based amplifier design overcomes errors associated with resistive current sensing, particularly those resulting from high commonmode voltages. Many current-sensing ICs are available for ...

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 ...

Sensing of current going to a load is a critical and often mandatory requirement in many designs. While there are many contact and non-contact ways to accomplish this sensing, such as using ...

Editor’s note: I am pleased to have Gustavo Castro as this month’s RAQ author. Castro is a system applications engineer in the Linear and Precision Technology Group in Wilmington, MA. His main ...
