General Description

The AMC1200 and AMC1200B are precision isolation amplifiers 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 (AMC1200B) or 4000 VPEAK (AMC1200) according to UL1577 and VDE V 088410.

Used in conjunction with isolated power supplies, these devices prevent noise currents on a high common mode voltage line from entering the local ground and interfering with or damaging sensitive circuitry.

Key Features

  • 1 ±250-mV Input Voltage Range Optimized for Shunt Resistors.
  • Very Low Nonlinearity: 0.075% Maximum at 5 V.
  • Low Offset Error: 1.5 mV Maximum.
  • Low Noise: 3.1 mVRMS Typical.
  • Low High-Side Supply Current: 8 mA Maximum at 5 V.
  • Input Bandwidth: 60 kHz Minimum.
  • Fixed Gain: 8 (0.5% accuracy).
  • High Common Mode Rejection Ratio: 108 dB.
  • 3.3-V Operation on Low-Side.
  • Certified Galvanic Isolation:.
  • UL1577 and VD.
