Question

For a 10 bits ADC by Successive Approximation, how many comparisons are needed for the ADC to complete? 10 9 It depends on the analogue value. 1024One of the following statements on ADC in the ARM processor is incorrect. Which one? The four bits configuration for a ADC input pin are 0000. Configure RCC_APB2ENR register to enable the ADC clock. The ARM can take maximally 18 ADC inputs including the two internal channels. One pin from GPIO port D can be configured as an ADC input pin. The following codes are supposed to configure the ADC. ADC1 RIGHTARROW CR2 |= (7

Explanation / Answer

Question 1) Ans: For N-bit ADC we need N comparisons are needed for conversion

For 10 bit ADC you need 10 comparisons So Ans) A

For every comparision we will decide each bit value whether 0 or 1 in a 10 bit ADC
