Difference between DAC types-weighted resistor,R-2R ladder
The following diagram shows a 3 bit digital to analog converter implemented using a summing opamp amplifer. One important specification of a DAC is its resolution. It can be defined by the numbers of bits or its step size.
In this context, high-performance DACs have become crucial building blocks. Skip to search form Skip to main content. Topics Discussed in This Paper.

To analyse this circuit, first we observe that since the output is connected to V- through R fthe opamp is in a negative feedback configuration. From the table, we can conclude the following The invertwd can be thought of as a binary number, one that can run from 0 to 7.
Therefore the individual current values I2, I1, I0 are unaffected by the switch setting and the ladfer network circuit can be redrawn to the following.
