MLX90308CAB

MLX90308CAB Programmable Sensor Interface Features and Benefits Microprocessor-controlled signal conditioning for bridge-type sensors Suited for low-cost sensors: reduction of non-linearity by programmable coefficients External or internal temperature sensor for compensating temperature errors Versatile output signal ranges: 4, 5, 10, or 11VDC; 4 to 20 mA loop Mass calibration easy with 2400 or 9600 baud UART Power supply from 6 to 35VDC Applications Pressure transducers Accelerometers Temperature sensor assemblies Linear position sensors Ordering Information art No. MLX90308CAB MLX90308CAB Temperature Suffix L L Package LW UD* Option Temperature Range -40C to 140C Automotive -40C to 140C Automotive *UD denotes unpackaged die Description The MLX90308CAB is a dedicated microcontroller which performs signal conditioning 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 reprogrammable. Programming is accomplished by using a PC, with an interface circuit (level shifting and glue logic), and provided software. The application circuits can provide an output of an absolute voltage, relative voltage, or current. The output can be range limited with defined outputs when the signal is beyond the pr...
