Linear Current Sensor, Hall Effect, +/- 5A, SOIC-8Product OverviewThe ACS712 provides economical and precise solutions for AC or DC currentsensing in industrial, automotive, commercial, and communications systems. Thedevice package allows for easy implementation by the customer. The deviceconsists of a precise, low-offset, linear Hall sensor circuit with a copperconduction path located near the surface of the die. Applied current flowingthrough this copper conduction path generates a magnetic field which is sensedby the integrated Hall IC and converted into a proportional voltage. Deviceaccuracy is optimized through the close proximity of the magnetic signal to theHall transducer. A precise, proportional voltage is provided by the low-offset,chopper-stabilized BiCMOS Hall IC, which is programmed for accuracy afterpackaging.Low-noise analogue signal pathDevice bandwidth is set via the new FILTER pinSmall footprint, low-profile1.2 mR internal conductor resistanceOutput voltage proportional to AC or DC currents66 to 185 mV/A output sensitivityFactory-trimmed for accuracyExtremely stable output offset voltageNearly zero magnetic hysteresisRatio metric output from supply voltageApplicationsAutomotive, Sensing & Instrumentation, Industrial, Power Management,Communications & NetworkingProduct InformationQuiescent Current: 10mABandwidth: 80kHzSensor Case Style: SOICNo. of Pins: 8PinsSupply Voltage Min: 4.5VSupply Voltage Max: 5.5VOperating Temperature Min: -40°COperating Temperature Max: 85°CMSL: MSL 2 - 1 year
