Top Features

Typical Applications

Packaging

  • Ultralow thermal drift
    • Sensitivity ±1%
    • Offset ±5 mV
  • Industry-leading noise performance 
  • Very fast response time (2 μs) with 240kHz bandwidth
  • Industry-leading ESD and EOS performance 
  • Ultralow over/undershoot thanks to patented suppression circuit 
  • 1mm thin KT package 
  • OK package that's highly immune to vibration

The KT package is available with straight leads, as well as a lead-formed option that enables surface mount assembly. The ACS70311 is also available in a 4-pin SIP (suffix OK) package offering longer and thicker leads compared to the KT package, making it an ideal choice for current sensing modules and applications with high level of mechanical vibration.
