该系列器件可在独立于电源电压的–0.
3V至26V共模电压下感应分流电阻器上的电压降.
共有三种固定增益可供选择:50V/V、100V/V和200V/V.
该系列器件采用零漂移架构,偏移较低,因此在进行电流感测时能够将分流电阻器两端的最大压降保持在最低10mV的满量程.
这些器件由2.
7V至26V的单个电源供电,消耗的最大电源电流为100A.
所有版本的额定温度均为–40°C至125°C,并且提供了SC70-6和薄型UQFN-10两种封装.

5静静电电放放电电警警告告ESD可能会损坏该集成电路.
德州仪器(TI)建议通过适当的预防措施处理所有集成电路.
如果不遵守正确的处理措施和安装程序,可能会损坏集成电路.
ESD的损坏小至导致微小的性能降级,大至整个器件故障.
精密的集成电路可能更容易受到损坏,这是因为非常细微的参数更改都可能会导致器件与其发布的规格不相符.
