The AMC1302-Q1 is a precision isolated amplifier with a capacitive isolation barrier that has high immunity to magnetic interference. This barrier provides reinforced isolation of 5 kVRMS (maximum) with a very long lifetime and low power dissipation. When used with isolated power supplies, this device isolates components that operate on different common-mode voltage levels. Furthermore, the AMC1302-Q1 also protects lower-voltage devices from damage.

The input of the AMC1302-Q1 is optimized for direct connection to shunt resistors or other low voltage-level signal sources. The ±50-mV input voltage range allows significant reduction of the power dissipation through the shunt. Additionally, the low high-side supply current and voltage of the AMC1302-Q1 allow use of low-cost isolated power-supply solutions. The performance of the device supports accurate current control resulting in system-level power savings and in low torque ripple that is particularly important in motor control applications. The integrated input common-mode overvoltage and missing high-side supply voltage detection features of the AMC1302-Q1 simplify system-level diagnostics.
