Application Note
AN296181 - Determining the accuracy of a system requires knowledge of the error introduced by each component. When looking at Allegro current sensor datasheets, the total error line item is a good approximation of the worst-case error seen in application.
This application note describes multiple methods for measuring and characterizing system bandwidth, with a focus on the impulse response method. Allegro’s ACS720 is the perfect device to validate the test methods outlined here.
AN296182 - When measuring busbar current with a surrounding soft ferromagnetic concentrator cores, Allegro recommends using a linear IC, such as the A1365, A1367, or ACS70310, in conjunction with a ferromagnetic core for high-current measurement (above 200 A).
AN296190 - The data contained within this application note allows the user to effectively choose an Allegro current sensor package based on their system’s specifications.
