onsemi Current Sense Amplifiers

For wider range and more reliability

onsemi’s quality and reliability is brought to the world of current sense amplifiers with two series of devices that offer all the brand’s quality in build and innovation. These current sense amplifiers are built to measure voltage across shunts at common mode voltages with a wide range to work with. In addition, onsemi current sense amplifiers’ zero-drift architecture provides a low offset that enables current sensing with voltage drops across sense resistors as low as 10 mV full-scale. See the options below and find the optimal device for your project.

 

NCS210R/NCV210R

The onsemi NCS210R and NCV210R are ideal for end products like white goods, automotive, lighting, laptop/notebooks PC, fast chargers in smartphones and tablets, telecom DC-DC modules, e-cigarettes, computing servers, and more. Thanks to its capabilities to measure voltage across shunts at common−mode voltages from −0.3 V to 26 V, independent of supply voltage these devices come as an optimal solution in the market.
