Question

You have purchased an 8-bit R-2R digital to analog converter to control the joint position on a robotic arm (the position of which is proportional to the input voltage).

a) The DAC shows an output voltage of 1.21 V when the binary value 00100101 is applied. What is the full scale analog output range of this DAC in volts?
b) What voltage does the DAC output with a binary value of 11101010 applied?
c) If the joint rotates 8.6 degree
