I just found some cool ICs and wanted to let you know:
AS5046 by AMS
http://www.austriamicrosystems.com/03products/products_detail/AS5046/description_AS5046.htm
Basing on Hall sensors and a custom CORDIC processing engine they can sense the rotational position of a magnet with up to 12 bit resolution. The device comes in TSSOP-16 package and seems to be pretty straight-forward to use. Two different serial interfaces are offered (SPI and I2C), there are analog and PWM outputs as well.
AFAIR the position update rate is > 100 Hz in high res mode.
The manufacturer is offering free samples.

Hi jan,
Pretty impressive device. I love how the manufacturer goes out of the way to provide sdk and good examples, as well as all of the calculations you need to mount the magnet.
Good find. I will try to get some samples to play with.
Thanks!
Barry

Hi Jan
I use some AMS-devices and are very impressed by the performance and easy-of-use 
tests on those devices were done:
brushless-encoder out of 10bit 5043 for my powerbike and RCmodels, VSRengines, up to 30k rpm!
5046 for real 12bit position of servos and joysticks
12bit ADsampling up to 50ksps, made a LA/USBoszi out of this device
LDO for the wireless-device, superlow ripple without expencive filter
digital potentiometers controlled by I2C for sensorPCB/OPAMPs
linear amplification devices for analog-sensors
fast comparators for sensorlessBL-esc
now I placed my first "big" order to put those devices in commercial products.
