Which type of ADC uses a ramp signal for conversion?

• Delta-Sigma ADC

• Flash ADC

• Successive Approximation ADC

• Pipeline ADC

What is the principle behind the successive approximation ADC?

• Successive approximation ADC iteratively adjusts the digital output to match the input voltage by comparing it to a reference voltage and setting bits accordingly.

• Successive approximation ADC operates by averaging multiple samples of the input voltage.

• Successive approximation ADC converts the input voltage directly to a digital output without any adjustments.

• Successive approximation ADC uses a fixed reference voltage for all comparisons.
