MLX90320
Automotive Smart Sensor Interface IC
Subscribe to Product
(includes all related assets)
The MLX90320 is a versatile, fully integrated and programmable sensor interface solution mainly for automotive applications. The device provides amplification, calibration and temperature compensation for virtually all kinds of resistive bridge type sensors including pressure transducers, strain gauges and position sensors.
Melexis’ "Programmable Through Connector" concept for high-volume implementations, enables programming in the production environment post assembly.
With very few additional components the MLX90320 will amplify an analog ratiometric input signal to achieve the desired output signal. This output signal can be corrected for sensitivity and offset errors due to temperature effects.
An operating temperature range of -40°C to 150°C as well as various implemented clamping detection and fault/diagnosis modes, over-voltage and reverse polarity protection make the MLX90320 the perfect fit for automotive applications.
An Evaluation Board for this new MLX90320 chip is available.
