Analog and Digital Conversion/Hold Circuits

Hold Circuits edit

Zero Order Hold edit

The majority of DACs have "zero order hold" in their output. After feeding the data into the DAC, the DAC output jumps to a new output voltage. The DAC holds that output voltage constant for the entire sampling time, until a new value is fed into the DAC and the DAC output jumps to that new value.

First Order Hold edit

Fractional Order Hold edit
