Top Features

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
