Question

Complex the table in the below. Using the following definitions, calculate the maximum output voltage (Vout, max) and step size (ΔV) for 4-bit, 8-bit, and 16-bit R-2R ladder DACs in terms of Vref, then complete table 1 (with 6 decimal places).

Vout,maxis the maximum analog voltage that you can observe at the output of the DAC.
DAC equation: Vout = Vref

Example (2 bits):Vout,max = Vref · = Vref ·
= 0.75Vref

The step size AV is the difference between any two consecutive voltage levels in the DAC
output.
