   产品概述 返回TOPIEt嘉泰姆

The CXEP2325 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 CXEP2337x.  In conjunction with the CXEP2337x metering SoCs, the isolated sensor ICs offer unprecedented BOM cost reduction, immunity to magnetic tampering, and enhanced reliability for single-phase and polyphase applications The CXEP2325 isolated sensor ICs enable 4th-generation CXEP2337x 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 CXEP2337x and the isolated sensor ICs.These metering SoCs operate over the industrial temperature range and are available in an 8-pin lead(Pb)-free SO package.
