AMC1100DUB fully isolation amplifier

TEXAS INSTRUMENTS AMC1100DUB  Isolation Amplifier, 1 Amplifier, 200 µV, 4.25 kV, 2.7V to 5.5V, 4.5V to 5.5V, SOP, 8 Pins

The AMC1100DUB 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 is certified to provide galvanic isolation of up to 4250VPEAK, 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. The AMC1100 input is optimized for direct connection to shunt resistors or other low voltage level signal sources. The excellent performance of the device enables accurate current and voltage measurement in energy-metering applications. The output signal common-mode voltage is automatically adjusted to either the 3V or 5V low-side supply.

  • ±250mV Input voltage range optimized for shunt resistors
  • 0.075% Maximum at 5V Very low nonlinearity
  • 1.5mV Maximum low offset error
  • 3.1mVRMS Typical low noise
  • 2.5kV/µs Minimum transient immunity
  • Green product and no Sb/Br
