AMC1100 E-Metering Amplifier

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

Image of Texas Instruments' AMC1100 E-Metering AmplifierTexas 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.

Features Applications
  • ±250 mV input voltage range optimized for shunt resistors
  • Very low nonlinearity: 0.075% max at 5 V
  • Low offset error: 1.5 mV max
  • Low noise: 3.1 mVRMS typ
  • Low high-side supply current: 8 mA max at 5 V
  • Shunt resistor based current sensing in:
    • Energy meters
    • Green energy
    • Power measurement applications
