Question:

For the converter of Example 11-12, determine the digital output for VA = 1.345 V. Repeat for VA = 1.342 V.


Data from Example 11-12

Assume the following values for the ADC of Figure 11-13: clock frequency = 1 MHz; VT = 0.1 mV; DAC has F.S. output = 10.23 V and a 10-bit input. Determine the following values.

The digital equivalent obtained for VA = 3.728 V
