Additional Details:

The AD5700-5Z uses iCoupler® technology to provide robust galvanic isolation between the HART communication interface and the host controller. This isolation protects sensitive circuitry from high voltages and ground loops commonly found in industrial environments. The device operates from a single 3.0 V to 3.6 V supply and consumes very little power. It also includes comprehensive diagnostic features to monitor system health and detect potential faults. The HART modem is fully compliant with the HART physical layer requirements, ensuring reliable communication over long distances.
