Learn about our reinforced isolated amplifier for voltage sensing  AMC1311-Q1.

Description

The AMC1301-Q1 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-Q1 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-Q1 device simplify system-level design and diagnostics.

The AMC1301-Q1 device is available in a wide-body 8-pin SOIC (DWV) package.
