General Description
The MLX90329 covers the most typical resistive type of Wheatstone bridge applications for use in an automotive environment. It is a mixed signal sensor interface IC that converts small changes in resistors, configured in a full Wheatstone bridge on a sensing element, to large output voltage variations
FEATUREs and Benefits
◾ Sensor interface IC for use in harsh
automotive environments
◾ High EMC robustness
◾ Possibilities to achieve outstanding overall
sensor performances
◾ SENT output with option for pressure,
calibrated on chip or external NTC
temperature information
◾ Outstanding accuracy for factory
calibrated NTC within ±1°C
