More detail for the lurkers:

It's a 10 bit unary ADC, and can be used as such. I've done it before.

Classic flash ADCs used 2^n comparators and a resistor string in the
front end. The resulting (say, 256 bit) thermomometer code was then
mapped into binary. I think somebody did that at 10 bits, 1024
comparators.

Nowadays people tend to do cleverer things.
