AMC1100DUBR

The AMC1100 is a high-precision isolated amplifier that isolates the output and input circuits through a silicon dioxide (SiO₂) isolation barrier with high magnetic field immunity. According to the DIN VDE V 0884-11: 2017-01 and UL1577 standards, this isolation barrier is certified to provide electrical isolation up to 4250VPEAK. When used with an isolated power supply, this device can prevent noise currents on high common-mode voltage lines from flowing into the local ground and interfering with or damaging sensitive circuits. The input of the AMC1100 is optimized for direct connection to shunt resistors or other low-voltage level signal sources. With the excellent performance of this device, accurate current and voltage measurements can be achieved in power metering applications. The common-mode voltage of the output signal is automatically adjusted to the 3V or 5V low-side power supply. The AMC1100 is fully rated for operation over the extended industrial temperature range (-40°C to +105°C) and is available in SMD-type wide-body small outline integrated circuit (SOIC)-8 (DWV) and gullwing-8 (DUB) packages.
