Hall element unequal potential compensation unequal potential has the same order of magnitude as Hall potential, and sometimes even exceeds Hall potential. ADUM1201ARZ is extremely difficult to eliminate unequal potential in practical applications, so compensation must be used. . Since the unequal potential is consistent with the unequal resistance, a method of analyzing the resistance can be used to find a compensation method for the unequal potential. As shown in the figure, A and B are excitation electrodes, C and D are Hall electrodes, and the pole distribution resistances are represented by R i , R 2 , R 3 and R4, respectively. Ideally, R i =R 2 =R 3 =R 4 , and zero current is zero (or zero resistance is zero). In fact, due to the existence of the unequal resistance, the four resistor values ​​are not equal, and can be regarded as the four bridge arms of the bridge, and the bridge is unbalanced. To achieve equilibrium, resistors can be placed in parallel on the bridge arm with a large resistance (see Figure a) or on both bridge arms (see Figure b). A business tablet must have powerful business functions. At present, users use tablet products more for entertainment, and insufficient development of commercial value has become a major factor restricting the development of tablet computers. Many far-sighted terminal manufacturers have set their sights on the business tablet field. Business Tablet,4k Tablet,5G Tablet Jingjiang Gisen Technology Co.,Ltd , https://www.gisengroup.com
Generally speaking, when business users choose tablet PC products, they still focus on "regular items" such as processor, battery, operating system, and built-in applications, especially office software applications, which are a good helper for business users.
First of all, there must be powerful office software such as customer management software, which can record customer data and related information anytime, anywhere. There is also a need for powerful marketing software, software marketing, reducing manual intervention, and one person can handle all the publicity and customer information.
