Czujnik prądu ACS714 Specification

  • Voltage digital logic supply: 4.5 V to 5.5 V
  • Supply current logical parts: 13
  • Sensitivity for power 5V: 0,185 V/A
  • Weight-1.3 g
  • Dimensions: 18 x 20.5 mm



The module consists of a printed circuit Board made for the system Allegro ACS714LLCTR-05B-T. The sensor operates based on the Hall effect. The chip can be powered from voltage range: 4.5 V to 5.5 V.


Basic module features:

  • The layout is designed for current flowing in both directions (from -5 to 5 A)
  • Due to the low resistance of the system (1.2 mΩ) and wire power loss is very small.
  • Through the use of Hall effect current paths are isolated from the parts of the puzzle.
  • The throttle range to 80 kHz with the possibility of reduction by adding an additional capacitor
  • Precision of 1.5% at room temperature.


Connection method

The sensor requires a voltage supply range from 4.5 V to 5 V, connected to terminals designated as VCC (+) and GND (ground). The output is a voltage signal proportional to the intensity of the measured current. When the voltage VCC equal to 5 Volts, the output from the centering half, i.e., 2.5 V. the output Value increases by 185 mV at 1 A if the strength of the measured current is positive, otherwise it decreases.

Additional filtering

The chip has an internal filter resistor is 1.7 k ohms, the circuit Board is the capacitor value of 1nF, which together form a low pass filter with cut-off frequency of 90 kHz. The user can change the filter when the capacitor is output onis called "filter". The boundary frequency can be calculated by the formula:


F = 1 / (2nRC) = 1 / (11kΩ * (1 nF + Cf))


where Cf is the capacitance of the capacitor wlutowanego insights "filter".
