For one thing, I don't think there such a thing as a 1-bit ADC, because 
the ADC process does not employ the 1 bit process, (unless id does so
internally as a successive approximation converter).  

What he is asking is is there a commercially available (small qty)
1 bit DAC, as these are now widely available in CD players.

>Why would anyone make a whole-chip 1-bit convertor.

??? These are 8 or 12 or 16 (or more) bit ADC's that compute an
output voltage in a bit-wise manner, instead of the traditional
ladder-type resistor circuit.  They (supposedly) offer better
linearity and mono-tonicity than the regular kind of ADC, but I
doubt that they make an audible difference in CD players...
