Select the Statement That Best Describes the Input Resistor Values

Multiple Choice

Select the statement that best describes the input resistor values for a simple DAC using an op- amp as a summing amplifier.

A) They are binarily weighted with the LSB resistor having the largest value and the MSB having a value equal to the feedback resistor.
B) They are binarily weighted with the LSB resistor having a value equal to the feedback resistor and the MSB having the highest value.
C) Starting with the MSB resistor, the values decrease by a factor of 4 to the LSB resistor.
D) Starting with the LSB resistor, the values increase by a factor of 4 to the MSB resistor.
