AEC-Q100 qualified for automotive applications The ADA4558 is a fully integrated, sensor signal conditioner
IC for bridge sensors. The device provides digital nonlinearity
correction and temperature compensation via internal or external
sensed temperatures using on-chip correction and calibration
hardware that can be optimized for a specific bridge sensor.
The ADA4558 utilizes a fourth-order digital correction algorithm
and delivers a system accuracy of 0.1% full scale range (FSR) for
bridge sensors with second-order nonlinearity sensitivity. The …
