Top Features

Packaging

  • Differential current sensing cancels common mode fields, simplifying PCB layout
  • Two user-settable faults for fast short-circuit protection and slower overcurrent detection
  • Industry-leading noise performance with greatly improved bandwidth through proprietary amplifier and filter design techniques
  • Patented integrated digital temperature compensation circuitry allows high accuracy over temperature in an open loop sensor
  • 1.0 mΩ primary conductor resistance for low power loss and high inrush current-withstanding capability
  • Small footprint, low-profile SOIC16 package suitable for space-constrained applications
  • Integrated shield virtually eliminates capacitive coupling from current conductor to die due to high dV/dt voltage transients
  • 5 V single supply operation with 0-3 V output swing
  • Output voltage proportional to AC or DC current
  • Factory-trimmed sensitivity and quiescent output voltage for improved accuracy
  • 3600 Vrms Dielectric Strength certified under UL60950-1
  • High PSRR for noisy environments

The ACS720 is provided in a small surface-mount SOIC16 package. The leadframe is plated with 100% matte tin, which is compatible with standard lead (Pb) free printed circuit board assembly processes. Internally, the device is Pb-free, except for flip-chip high-temperature Pb‑based solder balls, currently exempt from RoHS.
