3 Description

The AMC1400-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 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-Q1 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 power factor correction (PFC) stages, DC/DC converters, traction inverters, and other applications that must operate at high common-mode voltages, high altitudes, or in environments with high pollution degrees.

The AMC1400-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.
