Microchip Technology LX34211
The LX34211 is a highly accurate inductive position sensor interface IC with features that simplify the sensor design for a wide range of applications. This IC has more automatic control gain and a dynamic calibration algorithm that makes it easier to design accurate sensors with larger air gap and more mechanical tolerances with less current. The device includes an integrated oscillator circuit for driving the primary coil of an inductive sensor, along with two independent analog conversion paths for conditioning, converting, and processing of sine and cosine analog signals from the secondary coils of the sensor.
