Description

The MLX90314AB 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.

Option

The application circuits can provide an

output of an absolute voltage, relative

voltage, or current. The output can be

range limited with defined outputs when

the signal is beyond the programmed

limits.
