Description
The MLX90308CCC 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.

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
