LX34070

The LX34070 is an inductive position sensor IC for high-speed and noise-immune automotive and industrial application and extremely flexible for other applications. The two output signals that represent the absolute position can be configured as single ended for reduced pin count or differential to maximize noise immunity in remote applications. The device uses PCB traces to both generate an magnetic excitation signal and detect the presence of a metal targets positioned within the generated magnetic field. The advantage of this is a magnetic field sensor that does not require magnets, delivers higher accuracy and is extremely immune to stray magnetic fields.

For remote sensor applications, the sensor module, which includes the LX34070 device and the inductive sensing mechanism, will communicate analog position information to a host processing system over a 6-wire cable; the necessary signals to the processor are power, ground and the two differential analog position signals. The LX34070 has flexible calibration options for many applications. For remote applications, the device is programmed through a power line VIN signal and verified from one of the output signals, eliminating the need for additional pins and signals. In an embedded application where the sensor is on the same PCB as other microcontrollers, the device can be calibrated via digital signals.

The LX34070 is offered in a 14-pin TSSOP package with AEC-Q100 certification to grade 0 with an extended operating range (-40°C to +160°C) making it suitable for a wide range of commercial, industrial, medical and/or automotive sensor applications.
