Question 1
What is the formula for output voltage in a Weighted Resistor DAC?
- V_out = -R_f * V_REF * (D_N-1/R_0 + D_N-2/(2R_0) + ...)
- V_out = R_f * V_REF * (D_N-1/R_0 + D_N-2/(2R_0) + ...)
- V_out = R_f + D_N-2/(2R_0)
💡 Hint: Focus on the roles of V_REF and R_f in the equation.
Question 2
True or False: R-2R DACs require a broad range of resistors for proper functionality.
- True
- False
💡 Hint: Think about what both types of DACs need to operate.
