The AMC1411-Q1 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-Q1 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, isolated voltage sensing in onboard chargers (OBC), DC/DC converters, traction inverters, or other applications that must operate at high common-mode voltages, high altitudes, or in environments with high pollution degrees.

The AMC1411-Q1 is offered in a stretched 8-pin SOIC package and is AEC-Q100 qualified for automotive applications and supports the temperature range from –40°C to +125°C.
