The AMC1411 is a precision, isolated amplifier with an output separated from the input circuitry by a capacitive isolation barrier that is highly resistant to magnetic interference. This barrier is certified to provide reinforced galvanic isolation of up to 7.5 kVRMS according to VDE V 0884-11 and UL1577 and supports a working voltage of up to 1600 VRMS.

The isolation barrier separates parts of the system that operate on different common-mode voltage levels and protects the low-voltage side from voltages that can cause electrical damage or be harmful to an operator.

The high-impedance input of the AMC1411 is optimized for connection to high-impedance resistive dividers or other high-impedance voltage signal source. The excellent DC accuracy and low temperature drift support accurate voltage sensing in DC/DC converters, solar or wind turbine inverters, AC motor drives, or other applications that must operate at high voltages, high altitudes, or in environments with high pollution degrees.

The AMC1411 is specified over the extended industrial temperature range from –40°C to +125°C and supports operation down to –55°C.
