AMC1100 E-Metering Amplifier



Texas Instruments AMC1100 E-Metering Amplifier

Texas Instruments' 4.25 kVPEAK, fully differential isolated amplifier for e-metering

Texas Instruments' AMC1100 is a precision isolation amplifier with an output separated from the input circuitry by a silicon dioxide (SiO2) barrier that is highly resistant to magnetic interference. This barrier has been certified to provide galvanic isolation of up to 4250 VPEAK, according to UL1577 and IEC60747-5-2. 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.   AMC1100 Datasheet
