These are several common ways of implementing an electronic ADC. A direct-conversion or flash ADC has a bank of comparators sampling the input signal in parallel, each firing for a specific voltage range. The comparator bank feeds a digital encoder logic circuit that generates a binary number on the output lines for each voltage range. ADCs of this type have a large die size and high power dissipation. They are often used for video, wideband … WebSpecification of D/A converters (DACs) Figure 34: The ideal response of a 3-bit DAC, showing the analogue output voltage as a fraction of the full scale output FS.

The successive-approximation analog-to-digital converter circuit typically consists of four chief subcircuits: 1. A sample-and-hold circuit to acquire the input voltage Vin. 2. An analog voltage comparator that compares Vin to the output of the internal DAC and outputs the result of the comparison to the successive-approximation register (SAR).
