Current Sensor Module A5

  • This current sensor board is based on the Allegro ACS712ELCTR-05A bi-directional hall-effect current sensor chip that detects positive and negative flowing currents in the range of minus 5 Amps to positive 5 Amps.
  • The board operates at 5V DC and the current flow through the sensor is converted to an output voltage starting at 1/2Vcc (or 2.5V) for no current flow and moves up 185mV per amp for positive current or down -185mV per amp for negative current.

For example:

  • The output voltage at +2 amps would be (2.5V + (0.185 * 2)) = 2.870 V
  • The output voltage at -5 amps would be (2.5V – (0.185 * 5)) = 1.575 V


  • 185 mV/A output sensitivity
  • 5.0 V, single supply operation
  • Output voltage proportional to AC or DC currents
  • Factory-trimmed for accuracy
  • Extremely stable output offset voltage
  • Nearly zero magnetic hysteresis
  • Ratiometric output from supply voltage
  • Low-noise analog signal path
  • Device bandwidth is set via the new FILTER pin
  • 5 µs output rise time in response to step input current
  • 80 kHz bandwidth
  • Total output error 1.5% at TA = 25°C
  • Small footprint, low-profile SOIC8 package
  • 1.2 mΩ internal conductor resistance
  • 2.1 kVRMS minimum isolation voltage from pins 1-4 to pins 5-8
