Spec

• ACS723 Breakout Board Low Current Version
• The ACS723 is a Hall effect current sensor from Allegro MicroSystems. This board can detect currents from very small currents around 10 mA to 5 A. Outputs the voltage corresponding to the AC/DC current flowing through the holes connected to the IP+/IP- pins on the board. The advantage of using Hall effect sensors is that the circuit being sensed and the circuit reading the sensor are electrically separated. Sensitivity can be adjusted by the onboard amplifier.
• The analog output of the ACS723 can be up to 80 kHz, but this board is set to 20 kHz to reduce noise when ***d at high gain. The full bandwidth of 80 kHz can be recovered by closing the JP1 (bandwidth selection) jumper on the back of the board.
• [Note]
• *Although the ACS723 can insulate up to 2.4 kV (RMS), the board is not designed for these high voltage applications.
