The CXEP2339 isolated sensor ICs enable 4th-generation CXEP2339 systems-on-chips (SoCs) to use nonisolating sensors such as resistive shunts without the need for costly and nonlinear isolation transformers or CTs. Isolation is provided by low-cost pulse transformers that form a bidirectional digital communication link between the CXEP2339 and the isolated sensor ICs.The CXEP2339 isolated sensor ICs contain a 22-bit delta-sigma ADC, an amplifier with differential inputs, a precision voltage reference, a temperature sensor, and a supply voltage generator that is energized by power pulses provided by the CXEP2339.  In conjunction with the CXEP2339 metering SoCs, the isolated sensor ICs offer unprecedented BOM cost reduction, immunity to magnetic tampering, and enhanced reliability for single-phase and polyphase applications.These metering SoCs operate over the industrial temperature range and are available in an 8-pin lead(Pb)-free SO package
