An 8-bi t di gi t al -r amp ADC wi t h a 40 mV resolution uses a clock frequency of 2.5 MHz and a comparator with VT = 1mV. The digital output for VA = 6.000 V is

- 1 0 0 1 0 1 1 1
- 1 0 0 1 0 1 1 0
- 1 0 1 1 1 1 0
- 1 0 1 1 1 1 1
Correct Option: A
(Digital value) × resolution > VA + VT
(Digital value) × 40 mV > 6.001 V = 6001 mV
Digital value > 150.025, 15110 = 100101112
