AMC1106E05 Delta-Sigma Modulators

The AMC1106 is a precision, delta-sigma (ΔΣ) modulator with the output separated from the input circuitry by a capacitive isolation barrier that is highly resistant to magnetic interference. The input stage of the AMC1106 is optimized for direct connection to shunt resistors or other low voltage-level signal sources commonly used in multiphase electricity me.

Features

•1 ±50-mV input voltage range optimized for current measurement with shunt resistors
• Manchester coded or uncoded bitstream options
• Excellent DC performance for high-precision sensing on system level:
  – Offset error and drift: ±50 µV, ±1 µV/°C (max)
  – Gain error and drift: ±0.2%, ±40 ppm/°C (max)
• 3.3-V operation for reduced power dissipation on both sides of the isolation barrier
• System-level diagnostic features
• High electromagnetic field immunity (see the ISO72x Digital Isolator Magnetic-Field Immunity application report)
• Safety-related certifications:
  – 5657-VPK basic isolation pe.
