MLX90323420mA current loop sensor interface IC

The MLX90323 is a sensor interface IC with 4-20 mA current loop output for sensors wired in bridge or differential configurations.Sensors that can be used include thermistors, strain gauges, load cells, pressure sensors, accelerometers, etc...The signal conditioning includes gain adjustment, offset control, high order temperature and linearity compensation. Compensation values are stored in EEPROM and are re-programmable. Programming is accomplished by using a PC, with an interface circuit (level shifting and glue logic), and provided software.The robust electrical design allows the MLX90323 to be used where most signal conditioning and sensor interface circuits cannot be used. Voltage regulation control is provided for absolute voltage and current modes (external FET required).The standard package is a plastic SO16W. The device is static-sensitive and requires ESD precautions.For further information, please contactDieter Verstreken, Buy At Digi-KeyBuy At Future ElectronicsFeatures and BenefitsMicroprocessor-controlled signal conditioning for bridge-type sensorsSuited for low-cost sensorsreduction of non-linearity by programmable coefficients External or internal temperature sensor for compensating temperature errors4 to 20 mA current loop outputMass calibration easy with 2400 or 9600 baud UARTPower supply from 6 to 35VDCAssetsDataSheetFile TypeSizeRevisionDateActionMLX90323PDF337.2 KB16/11/2008Software & ToolsFile TypeSizeRevisionDateActionCalibration software 90323EXE170.4 KB1.110/15/2008Hardware descriptionPDF471.0 KB1.210/15/2008Library descriptionPDF198.9 KB1.210/15/2008Software ManualPDF393.2 KB1.210/15/2008
