该放大器的共模范围几乎是电源电压的三倍(G = ?),因此非常适合要求高共模电压范围的单电源应用。内部电阻和输入端的ESD电路还为运算放大器提供过压保护。
AD8278和AD8279可以用作增益G = ?或G = 2的差动放大器。二者也可以用于高精度、单端配置中,提供同相和反相增益G = ??、?2、+3、+2、+1?、+1或+?。这些器件提供集成式精密解决方案,比分立解决方案尺寸更小、成本更低、性能更优。
AD8278和AD8279采用2.0 V至36 V单电源或±2 V至±18 V双电源供电。最大静态电源电流为200 μA,非常适合电池供电的便携式系统。
AD8278提供节省空间的8引脚MSOP和SOIC两种封装,AD8279则提供14引脚SOIC封装。二者的额定温度范围均为?40°C至+85°C工业温度范围,并且完全符合RoHS标准。
