Output voltage = Resolution × Decimal equivalent of binary Data.
K = Proportionality factor i.e. Resolution
bn = 1: if nth bit of digital input is 1
0 = If nth bit of digital input is 0
Resolution: It is a change in the analog voltage corresponding to the LSB bit increment at the input.
Explanation:
Refrence voltage (Vref):
Option 3 correct.
More information:
Error/Accuracy: Maximum error acceptance in ADC/DAC is 1 LSB bit which is equal to the resolution
Error ≤ resolution.
Full-scale voltage VFC = Resolution × maximum decimal.
VFC = Vr
