OVERVIEW

The MAX71071/MAX71071H are dual-channel isolated analog-to-digital converters ADCs for use with a compatible MAX71xxx host. The device provides current and voltage measurements to the host while the host provides control, command, and power to the MAX71071/MAX71071H. A pulse transformer provides the isolated data, clock, and power path between the device and host, eliminating the need for additional isolation components in the measurement subsystem.
