Features and Benefits:
  • Industry-leading noise performance through proprietary amplifier and filter design techniques
  • Integrated shield greatly reduces capacitive coupling from current conductor to die due to high dV/dt signals, and prevents offset drift in high-side, high voltage applications
  • Total output error improvement through gain and offset trim over temperature
  • Small package size, with easy mounting capability
  • Monolithic Hall IC for high reliability
  • Ultra-low power loss: 100 µΩ internal conductor resistance
  • Galvanic isolation allows use in economical, high-side current sensing in high voltage systems
  • AEC Q-100 qualified
  • 3.0 to 5.5 V, single supply operation
  • 120 kHz typical bandwidth
  • 3 µs output rise time in response to step input current
  • Output voltage proportional to AC or DC currents
  • Factory-trimmed for accuracy
  • Extremely stable output offset voltage
  • Nearly zero magnetic hysteresis
