Overview

The AMC1302 is aprecision isolated amplifier with a capacitive isolation barrier that has high immunity to magneticinterference. This barrier provides reinforced isolation of 5 kVRMS(maximum) with a very long lifetime and low power dissipation. When used with isolated powersupplies, this device isolates components that operate on different common-mode voltage levels.Furthermore, the AMC1302 alsoprotects lower-voltage devices from damage.

The input of the AMC1302 is optimized for direct connection to shunt resistors or otherlow voltage-level signal sources. The ±50-mV input voltage range allows significant reduction ofthe power dissipation through the shunt. Additionally, the low high-side supply current and voltageof the AMC1302 allow use oflow-cost isolated power-supply solutions. The performance of the device supports accurate currentcontrol resulting in system-level power savings and in low torque ripple that is particularlyimportant in motor control applications. The integrated input common-mode overvoltage and missinghigh-side supply voltage detection features of the AMC1302 simplify system-level diagnostics.
