SparkFun Hall-Effect Current Sensor Breakout - ACS712

7.95 €7.95

Availability: Retired

This is a breakout board for the fully integrated Hall Effect based linear ACS712 current sensor. The sensor gives precise current measurement for both AC and DC signals. Thick copper conductor and signal traces allows for survival of the device up to 5 times overcurrent conditions. The ACS712 outputs an analog voltage output signal that varies linearly with sensed current. The device requires 5VDC for VCC and a couple of filter capacitors. Please keep in mind that though the ACS712 is rated for 2.1kV isolation, the PCB it is on is not designed for that type of voltage. Please keep that in mind if you are using this breakout in high voltage applications.Features:x05B (5 Amp) versionLow noise analog signal pathDevice bandwidth is set via the FILTER pin5us output rise time in response to input current80kHz bandwidth1.5% output error at 25 degrees C1.2mOhm internal conductor resistance5.0 VDC, single supply operation185 mV/A output sensitivityOutput voltage proportional to AC or DC currentsFactory-trimmed for accuracyExtremely stable output offset voltageNearly zero magnetic hysteresisRatiometric output from supply voltageDocuments:SchematicEagle FilesACS712 DatasheetWiring ExampleGitHub
