Io= (Vref/R1)×[ (D7/2)+(D6/4)+(D5/8)+(D4/16)+(D3/32)+(D2/64)+(D1/128)+(D0/256)]. 2. Determine the maximum value of output current of the DAC in MC1408?
A. 0.773×(Vref/R1)
B. 0.448×(Vref/R1)
C. 0.996×(Vref/R1)
D. 0.224×(Vref/R1)
Answer:A
Io= (Vref/R1)×[ (D7/2)+(D6/4)+(D5/8)+(D4/16)+(D3/32)+(D2/64)+(D1/128)+(D0/256)]. 2. Determine the maximum value of output current of the DAC in MC1408?
A. 0.773×(Vref/R1) B. 0.448×(Vref/R1) C. 0.996×(Vref/R1) D. 0.224×(Vref/R1)
Explanation: The output current of DAC is the maximum when all the inputs are logic 1.
