Allegro Microsystems (ACS712ELCTR-30A-T) Linear Current Sensor

Linear Current Sensor, Hall Effect, 30A Sensing Current, SOIC-8Product OverviewThe ACS712ELCTR-30A-T is a fully integrated, hall effect based linear currentsensor IC in 8 pin SOIC package. It provides economical and precise solutions.The device 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 Becomes Hall IC which is programmed for accuracy afterpackaging.Low noise analogue signal pathDevice bandwidth is set via new filter pin5µs output rise time in response to step input current1.5% at TA = 25°C total output error1.2mohm internal conductor resistance2.1KVrms minimum isolation voltage from pins 1-4 to pins 5-866mV/A output sensitivityOutput voltage proportional to AC or DC currentsFactory-trimmed for accuracyExtremely stable output offset voltageNearly Zero Magnetic HysteresisRatiometric Output from Supply VoltageApplicationsSensing & Instrumentation, Industrial, Commercial, Communications & Networking,Motor Drive & Control, Power Management, SafetyProduct 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°C
