Homework Statement
The input bits 0 and 1 are represented by 0 volts and 5 volts respectively. The OP-AMP is ideal, but all the resistances and the 5 volts inputs have a tolerance o f ± 10%. The specification (rounded to the nearest multiple of 5%) for the tolerance of the DAC is??
In this question all I want to know is what is the physical significance of the term tolerance as given for the resistor , what's the purpose?? And we have to find tolerance of dac , what does this mean??
Homework Equations
In the solution , they found out the output voltage of op-amp and put the values of the individual tolerances..how they got to know that we have to find output voltage's tolerance from the given problem??
Voutput = -Vr [Rf/R] where Vr is the reference voltage [/B]
