General description

The MLX90320 covers the most typical resistive type of Wheatstone bridge applications for use in an automotive environment. It is a monolithic silicon analog sensor interface that converts small changes in resistors, configured in a full Wheatstone bridge on a sensing element, to large output voltage variations.

Features and Benefits

❐ Suited cost optimized sensors: gain and offset correction by programmable coefficients

❐ Higher order temperature compensation provided for both gain and offset

❐ External or internal temperature sensor for compensation of temperature errors

❐ Over-voltage protection

❐ Fault detection and clamping levels

❐ Ratio-metric output: 0 to 5V

❐ Single Pin Digital Programming

❐ Fully analog signal path

❐ RoHS compliant

Applications Examples

❐ Pressure transducers, strain gauges, accelerometers, position sensors, etc.

❐ Steering systems (e.g. torque sensors)

❐ Safety restraints systems (e.g. seat occupant detection)

❐ Braking systems (e.g. ABS, force)

❐ Comfort systems (e.g. air conditioning)

❐ Engine management (e.g. injection)

❐ Any bridge type sensor
