The AMC1301 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 0884-11 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 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 simplify
system-level design and diagnostics.
The AMC1301 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. The AMC1301S is specified over the temperature range of –55°C to +125°C.
