You are given a 12-bit signed unsigned A/D with reference voltages tied to 3.3V and GND. If 2.75V is input to the A/D what is the expected digital output? What is the smallest value that can be measured? Repeat #1 above assuming a signed 12-bit A/D. What is the smallest voltage that car be measured for the A/D in #2 and the A/D in this question? What is the smallest value that can be measured? What is the difference between the ADC in #1 and #2? What is the trade-off?
