Question:

What would happen in the ADC of Problem 11-24 if an analog voltage of VA = 10.853 V were applied to the input? What waveform would appear at the D/A output? Incorporate the necessary logic in this ADC so that an “overscale” indication will be generated whenever VA is too large.

Data from Problem 11-24

An eight-bit digital-ramp ADC with a 40-mV resolution uses a clock frequency of 2.5 MHz and a comparator with VT = 1 mV. Determine the following values.

(a) The digital output for VA = 6.000 V

(b) The digital output for 6.035 V

(c) The maximum and average conversion times for this ADC
