Analog and Digital Converters - Technical MCQs
Q1: What is the major advantage of the R/2R ladder digital-to-analog (DAC), as compared to a binary-weighted digital-to-analog DAC converter?A
It only uses two different resistor values.
B
It has fewer parts for the same number of inputs.
C
Its operation is much easier to analyze.
D
The virtual ground is eliminated and the circuit is therefore easier to understand and troubleshoot.
ANS:A - It only uses two different resistor values. This is main advt. of R/2R over binary weighted |
