SparkFun Current Sensor Breakout ACS723

SparkFun Current Sensor Breakout ACS723
Features-

1. Analog output with bandwidth adjustable to 80kHz.
2. The bandwidth on the ACS723 Sensor Breakout width filter has been set to 20kHz to reduce noise when using at high gains. The full 80KHz bandwidth that the sensor is capable of can be recovered by closing the JP1 (Bandwidth Select) jumper on the back of the board. See either the ACS723 schematic or the ACS723 Low Current schematic for more details.
3. Measures DC and AC currents.
4. Full electrical isolation of measured and sensed circuits.
5. The version without the op-amp has a base sensitivity of 400mV/A.
