I did a bit of checking with TI on the status of the DAC7714UB. It is
still in allocation pending conversion to a new tester which is
scheduled in Q1 2008. I expect it will come off allocation shortly
after that. I did not check with Analog Devices as to the
availability of the AD5726YRWZ.
I did manage to obtain a small quantity of DAC7714U, DAC7714UB, and
AD5726YRWZ parts. I'd be happy to work with whoever organizes another
ExpressPCB board purchase to coordinate DACs with the PCBs. There are
slight variations in specs between these parts but I think all would
work fine in this application.
