CXEP2339隔离传感器IC使第四代CXEP2339片上系统（SOC）能够使用非隔离传感器，如电阻分路，而无需昂贵的非线性隔离变压器或CT。隔离由在CXEP2339和隔离传感器集成电路之间形成双向数字通信链路的低成本脉冲变压器提供。CXEP2339隔离传感器集成电路包含一个22位delta-sigma ADC、一个带差分输入的放大器、一个精确的电压基准、一个温度传感器和一个电源电压发生器由CXEP2339提供的电源脉冲供电。与CXEP2339测量SOC一起，隔离传感器IC为单相和多相应用提供了前所未有的材料清单成本降低、抗磁干扰能力和增强的可靠性。这些测量SOC在工业温度范围内运行，可在8针引线（Pb）自由SO封装中使用
