MLX90320 - Melexis Microelectronic

MLX90320 Automotive small sensor interface

Wheatstone bridge on a sensing element, to large output voltage variations. The signal conditioning includes gain adjustment, offset control and second order temperature compensation in order to accommodate variations of the different resistive sensing elements. Compensation values are stored in EEPROM and can be reprogrammed with an interface circuit and p.

Features

 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 o.
