The AMC1351-Q1 is a precision, isolated amplifier with an output separated from the input circuitry by an isolation barrier that is highly resistant to magnetic interference. This barrier is certified to provide reinforced galvanic isolation of up to 5 kVRMS according to VDE V 0884-11 and UL1577, and supports a working voltage of up to 1.5 kVRMS.

The isolation barrier separates parts of the system that operate on different common-mode voltage levels and protects the low-voltage side from potentially harmful voltages and damage.

The high-impedance input of the AMC1351-Q1 is optimized for connection to high-impedance resistive dividers or other voltage signal sources with high output resistance. The excellent accuracy and low temperature drift supports accurate DC voltage sensing in DC/DC converters, frequency inverters, motor-drives, or other applications that must support high common-mode voltages.

The AMC1351-Q1 is offered in a wide-body 8-pin SOIC package and is AEC-Q100 qualified for automotive applications and supports the temperature range from –40°C to +125°C.
