The ACS712 sensor reads the current value and converts it into a relevant voltage value. The measurement sensitivity for 20A model is 100mV/A. The sensor can measure positive and negative currents (range -20A — +20A), and power supply is 5V for the sensor, and the middle sensing voltage is 2.5V when no current.
- Low-noise analog signal path
- 5 ?s output rise time in response to step input current
- 80 kHz bandwidth
- Total output error 1.5% at TA= 25?C
- 0V single supply operation
