1. Design an 8-Bit DAC Circuit - Calculate the values for all resistors
2. Include calculations and schematic in a Word document
Vout = Vref × VAL / 2n
For 8 bit DAC, n = 8 and hence. With Vref = 3.3 V (typical CMOS logic 1 voltage), Vout will vary between.
Minimum (single step) VAL = 1
Vout = 3.3 × 1 / 28 volts
Maximum output VAL = 28- 1
Vout = 3.3 × (28- 1) / 28 volts
