APPLICATIO S I FOR ATIO
Output Driver Power
Separate output power and ground pins allow the output
drivers to be isolated from the analog circuitry. The power
supply for the digital output buffers, OV
to the same power supply as for the logic being driven.
For example, if the converter is driving a DSP powered by
