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 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 application circuits can provide an output of an absolute, relative or current voltage. The output can be range limited with defined outputs when the signal is beyond the programmed limits. Other features include alarm outputs and level steering.

The robust electrical design allows our MLX90314 to be used where most signal conditioning and sensor interface circuits cannot be used. Voltage regulation control is provided for absolute voltage and current modes (external field-effect transistor or FET required).

The standard package is a plastic SO16W. The device is static-sensitive and requires electrostatic discharge (ESD) precautions.
