The AMC1301 device 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 7
kVPEAK according to VDE V 0884-10 and UL1577. Used in conjunction with
isolated power supplies, this device prevents noise currents on a high common-mode voltage line
from entering the local ground and interfering with or damaging sensitive circuitry.
The input of the AMC1301 device 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 motor control
applications, lower torque ripple. The integrated common-mode overvoltage and missing high-side
supply voltage detection features of the AMC1301 device simplify system-level design and
The AMC1301 device is fully specified over the extended industrial temperature range of
40°C to +125°C and is available in a wide-body 8-pin SOIC (DWV) package.
