Description

The MAX78700 is an isolated analog-to-digital converter (ADC) for use with a compatible MAX78xxx energy measurement processor. The device provides current and voltage measurements to the host while the host provides control, command, and power to the MAX78700. A pulse transformer provides the isolated data and power path between the device and host, eliminating the need for additional isolation components in the measurement subsystem.
