Try these first

1. 1.

   What does a Binary-Weighted Resistor DAC use for conversion?

   Hint

   Think about the binary system.

2. 2.

   Why is precision important in this DAC design?

   Hint

   Consider what happens if the resistors are not accurate.

3. 3.

   What is the fundamental design of the Binary-Weighted Resistor DAC based on?

   • Voltage levels
   • Resistor values
   • Capacitance

   Hint

   Reflect on the weighting system used in this DAC.

4. 4.

   True or False: The Binary-Weighted Resistor DAC is ideal for high-resolution applications due to its simplicity.

   • True
   • False

   Hint

   Consider the limitations we discussed around precision.

5. 5.

   Consider a Binary-Weighted Resistor DAC with digital inputs of 3 (0011 binary). If the reference voltage is 5V, what will be the analog output? Calculate the output considering your resistor values.

   Hint

   Think about how each binary digit changes the voltage output.

6. 6.

   If you wanted to improve the performance of a Binary-Weighted Resistor DAC in an application that requires higher resolutions, what strategies would you implement?

   Hint

   Consider what improvements could address the scaling limitations.
