The AMC1300 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 5 kVRMS according to VDE V 0884-11 and UL1577. Used in conjunction with isolated power supplies, this isolated amplifier separates parts of the system that operate on different common-mode voltage levels and protects lower-voltage parts from damage.

The input of the AMC1300 is optimized for direct connection to shunt resistors or other low voltage-level signal sources. The excellent performance of the device supports accurate current control resulting in system-level power savings and, especially in . The integrated common-mode overvoltage and missing high-side supply voltage detection features of the AMC1300 simplify system-level design and diagnostics.

The AMC1300 is offered with two performance grade options: the AMC1300B is specified over the extended industrial temperature range of –55°C to +125°C, and the AMC1300 for operation at –40°C to +125°C.
