ACS711 Current Sensor Carriers
 |
 |
We are offering these breakout boards with support from Allegro Microsystems as an easy way to use or evaluate their ACS711EX Hall effect-based, electrically isolated current sensors. The following list details some of the sensor’s key features:
- Hall effect-based sensor with electrically isolated current path allows the sensor to be inserted anywhere along the current path and to be used in applications that require electrical isolation.
- Conductive path internal resistance is typically 0.6 mΩ, and the PCB is made with 2-oz copper, so very little power is lost in the board.
- 100 kHz bandwidth analog output voltage proportional to AC or DC currents.
- Good accuracy and reliability: factory calibration results in a typical total output error of ±5% at room temperature, the output offset voltage is extremely stable, and the sensor has zero magnetic hysteresis.
- Overcurrent FAULT output latches low when current magnitude exceeds the optimized sensing range.
- Operating temperature range of -40°C to 125°C.
- 0.7″×0.8″ carrier board offers a variety of ways to insert it into the current path and 0.1″-pitch (breadboard compatible) power, ground, and output pins.
They operate from 3 V to 5.5 V, so they can interface directly with 3.3 V and 5 V systems.
