The AMC3301-Q1 is a precision, isolated amplifier, optimized for shunt-based current measurements. The fully integrated, isolated DC/DC converter allows single-supply operation from the low-side of the device which makes the device a unique solution for space-constrained applications. The reinforced capacitive isolation barrier is certified according to VDE V 0884-11 and UL1577 and supports a working voltage of up to 1.2 kVRMS.

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

The input of the AMC3301-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 measurements in the temperature range from –40°C to +125°C.

The integrated DC/DC converter fault-detection and diagnostic output pin of the AMC3301-Q1 simplify system-level design and diagnostics.
