BASIC LINEAR DESIGN 6.4 On the back end, since the output of the DAC is often a current, an op amp is often added to perform the current-to-voltage (I/V) conversion. On the front end a voltage reference is often added. Process limitations did not allow the integration of all these sub-blocks to occur at once.
