The AMC3301 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 parts of the system that operate on different common-mode voltage levels and protects lower-voltage parts from damage.
The input of the AMC3301 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 AMC3301, and makes the device a unique solution for space-constrained applications.
The excellent performance of the device supports accurate current monitoring and control, resulting in system-level power savings and, especially in motor control applications, low torque ripple. The integrated input common-mode overvoltage and DC/DC converter operation fault detection features of the AMC3301 simplify system-level design and diagnostics.
The AMC3301 is specified over the extended industrial temperature range of –40°C to +125°C.
