Column clock for LSB and MSB Analog blocks of 8 bit DAC

Answer:

Question: What is the relation between column clocks of LSB and MSB analog blocks in the implementation of an 8 bit DAC?

Response:The column clock for the LSB and MSB blocks of an 8 bit or 9 bit DAC should be the same.  When the DAC is placed vertically in a single analog column, this is automatically taken care of.  If the DAC is placed in two analog columns in horizontal configuration, then make sure that the column clock for both the analog columns are the same.
