#184790 - RE:#184789 - State the actual requirement!
Responding to: Andy Neil's previous message
What it mean is that i need to use a 12-bit DAC, while even if i get a decent 9 or 10 bit actual / real resolution out of it even then it is ok for my application.

For the requirement, i already mentioned - I need to know if there is a way to avoid using multiple DACs for the multiple analog outputs, AND if there might exist a "fancy" way of doing the same thing with perhaps 1 DAC and multiple S/H amps, some fancy multiplexing or high-speed switching.
