What type of resistor network produces an output voltage that is properly weighted to a digital input?

The output voltage that is properly weighted to a digital input is best achieved through an R-2R Ladder DAC (Digital-to-Analog Converter). This type of network uses a repeating structure of resistors arranged in a ladder-like configuration, consisting of only two distinct resistor values, R and 2R. This simplicity allows for a straightforward implementation while ensuring that each bit contributes a weighted fraction of the reference voltage to the output.

In an R-2R Ladder, each bit in a digital input controls a switch that connects either to a high or low voltage. The unique characteristic of the R-2R network is that it efficiently sets up an output voltage that effectively translates the binary input into a corresponding analog voltage level. Each switch's contribution to the output voltage is determined by its position in the ladder, giving digital inputs a properly weighted analog output.

The other options encompass different concepts. A voltage divider produces a fixed output based on the resistance values and does not inherently produce a weighted output based on digital input levels. A parallel resistor network does not focus on bit-level contribution but rather combines resistances that lead to a simple voltage output without the discrete control required for a DAC. Lastly, while binary weighted resistors can also produce a weighted output, the
