Does anyone know where I can get a tiny (smaller the better) digital compass that can give an analog value output for an ADC on a microcontroller?
If it outputted a PWM, I could run that into a capacitor for an output analog voltage . . .
the best I can find is this but its been around for years and its still a little too big for me:

Admin,
This one is I2C, but it certainly fits the tiny criteria:

This one is true analog:

Nice thing with that one - if it works for you, you can build your own board - the 2-axis chip itself is cheap and tiny...
