Description for the AMC3302

The AMC3302 is a precision, isolated amplifier with a fully integrated, isolated DC/DC converter that allows single-supply operation from the low-side of the device. The reinforced capacitive isolation barrier is certified according to VDE V 0884-11 and UL1577 and separates sections of the system that operate on different common-mode voltage levels and protects low-voltage domains from damage.

The input of the AMC3302 is optimized for direct connection to shunt resistors or other low voltage-level signal sources. The integrated isolated DC/DC converter allows flexible placement of the shunt and the AMC3302, and makes the device a unique solution for space-constrained applications.

The excellent performance of the device supports accurate current monitoring and control, which is an important feature to achieve low torque ripple in motor control applications. The integrated DC/DC converter fault-detection and diagnostic output pin of the AMC3302 simplify system-level design and diagnostics.

The AMC3302 is specified over the industrial temperature range of –40°C to +125°C.
