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 and other sensors. The signal conditioning includes gain adjustment, offset control, high order temperature and linearity compensation.
Compensation values are stored in Electrically Erasable Programmable Read-Only Memory (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 output of the sensor bridge is amplified via offset and gain amplifiers and then converted to the correct output signal form in one of the output stages. Two I/O pins are available for analog inputs or digital outputs. These pins can be used for alarms on various points on the analog signal path and built-in or external temperature values.
