The MLX90314AB is a dedicated microcontroller which performs signal conditioning for sensors wired in bridge or differential configurations. Sensors MLX90314AB 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 of MLX90314AB is accomplished by using a PC, with an interface circuit (level shifting and glue logic), and provided software.
