Maxim 71M6xxx Isolated Sensor ICs

Maxim 71M6xxx Isolated Sensor ICs eliminate the need for costly current transformers in electric meter designs using the Teridian 4th-generation polyphase-metering 71M654x systems-on-chips (SoCs). Isolation is provided by low-cost pulse transformers that form a bidirectional digital communication link between the 71M654x SoCs and the 71M6xxx Isolated Sensor ICs.
