- Fully specified over the extended industrial temperature range: –40°C to +125°C
The AMC1400 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 7.5 kVRMS according to DIN EN IEC 60747-17 (VDE 0884-17) and UL1577, and supports a working voltage of up to 2 kVRMS.
The isolation barrier separates parts of the system that operate on different common-mode voltage levels and protects the low-side from voltage levels that can cause electrical damage and are potentially harmful to an operator.
The input of the AMC1400 is optimized for direct connection to a low-impedance shunt resistor or other low-impedance voltage source with low signal levels. The excellent DC accuracy and low temperature drift supports accurate current control in DC/DC converters, frequency inverters, AC motor drives, and other applications that must operate at high voltages, high altitudes, or in environments with high pollution degrees.
The AMC1400 is offered in a stretched SOIC package and is specified over the extended industrial temperature range from –40°C to +125°C .
