Overview
MLX90320 Automotive Sensor Interface 1.
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 2.
Application 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 3.
