General Description
The MLX90314 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 re- programmable. Programming is accomplished by using a PC, with an interface circuit (level shifting and glue logic), and provided software.

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

APPLICATION Examples
◾ Pressure transducers
◾ Accelerometers
◾ Temperature sensor assemblies
◾ Linear position sensors
