校准偏移寄存器的DS2761

摘要： DS2761的包含电流偏移寄存器，可以消除由设计师利用固有的偏移量由目前的A / D内部的IC 。然而，这个寄存器的校准不当，可以提高电流测量精度否定有任何积极的作用，尤其是在低电流。本应用笔记介绍给读者如何正确在完全组装的电池校准的设备，以确定正确的值应该被放置到当前偏移寄存器的DS2761上的步骤，循序渐进的方式。虽然是专为写入DS2761的应用笔记，它也是适用的DS2751 。

APPLICATION NOTE 224
Calibrating the Offset Register of the DS2761


Abstract: The DS2761 contains a current offset register that can be utilized by the designer to eliminate inherent offset introduced
by the current A/D within the IC. Improper calibration of this register, however, can negate any positive effect it has on increasing
the accuracy of the current measurements, especially at low currents. This application note describes to the reader a step-by-
step approach on how to properly calibrate the device within the fully assembled battery pack in order to determine the correct
value that should be placed into
