Io =(VR/R)× (d1/21 +d2/22 + ……dn/2n). 4. In a D-A converter with binary weighted resistor, a desired step size can be obtained by
A. Selecting proper value of VFS
B. Selecting proper value of R
C. Selecting proper value of RF
D. All of the mentioned
Answer:A
Io =(VR/R)× (d1/21 +d2/22 + ……dn/2n). 4. In a D-A converter with binary weighted resistor, a desired step size can be obtained by
A. Selecting proper value of VFS B. Selecting proper value of R C. Selecting proper value of RF D. All of the mentioned
Explanation: The size of the steps depends on the value of RF, provided that the maximum output voltage does not exceed the saturation level of an op-amp. 5. Determine the Full scale output in a 8-bit DAC for 0-15v range?
