Product Description

This is a breakout board for the fully integrated Allegro ACS758 Hall Effect-based linear current sensor. The sensor gives precise current measurement for both AC and DC signals. The module uses extra-thick copper to allow for continuous high-current use ... up to 50A.
The ACS758 outputs an analogue voltage output signal that is proportional with the current flowing through it.
  • Arduino interface compatible
  • 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
  • Total output error improvement through gain and offset trim over temperature
  • Monolithic Hall IC for high reliability
  • Ultra-low power loss: 100 μΩ internal conductor resistance


  • Operating Voltage(analog): 3.3-5V
  • Peak Measuring Voltage: 3000V(AC), 500V(DC)
  • Current Measuring Range: up to 50A
  • Sensitivity: 40 mV/A
  • Operating Temperature: -40~150°C
  • Dimensions: 34x34mm
