IC revision1

Description

The MAX78700 is an isolated analog-to-digital converter(ADC) for use with a compatible MAX78xxx energy measurementprocessor. The device provides current andvoltage measurements to the host while the host providescontrol, command, and power to the MAX78700. Apulse transformer provides the isolated data and powerpath between the device and host, eliminating the needfor additional isolation components in the measurementsubsystem.
