Advise me on inductive position sensor IC's

[MrMetthew]

Hi everyone,

I was at embedded world trade fair in Germany last week. I was looking for some 2d/3d hall sensor IC's. But then I stumbled upon a company offering inductive position sensing IC's. This looks very promising to me because of little  interference between sensors compared to magnetic sensors. I was just exploring the technology and wondered if any of you knew other companies that offer ic solutions for this. Any other insights on inductive position sensing versus magnetic/hal sensing are welcome!

Thanks! Link to see the IC I was talking about:

TI also has their LDC1xxx range. They're very capable sensors, but finicky. If the environment is just right, you can get some impressive accuracy out of them. If the environment is not so good... well, your measurements will tell you a lot about said environment!

One of the more interesting things is that there are two viable types of target: conductive materials and magnetizable materials. They have opposite effects on mutual inductance, and therefore on sensor reading. This can make for some interesting debugging.
