Top Features

Packaging

  • High-bandwidth 250 kHz analog output
  • Less than 2 μs output response time
  • 3.3 V and 5 V supply operation
  • Ultralow power loss: 200 μΩ internal conductor resistance
  • Industry-leading noise performance and increased
  • Greatly improved total output error through digitally programmed and compensated gain and offset over the full operating temperature range
  • Small package size, with easy mounting capability
  • Monolithic Hall IC for high reliability
  • Output voltage proportional to AC or DC currents
  • Factory-trimmed for accuracy
  • Extremely stable zero amp output offset voltage over temperature and lifetime

The ACS72981 family is lead (Pb) free. All leads are plated with 100% matte tin, and there is no Pb inside the package. The heavy gauge leadframe is made of oxygen-free copper.
