On the Beaglebone Black, what is the most current that the 1.8V analog rail (pin 32 on header P9) can supply?
I can't find it in the System Reference Manual. I would've expected to find it in section 6.1.9, "Power Rails".
I want to use it with a voltage divider to get a 0.9V source. I plan to use it like this:
With two 10k resistors and the op-amp buffer, the current should be 90 uA -- very small.
