The single-pipeline architecture uses 6 ADC/DAC stages and one final flash ADC. Each stage produces a
resolution of 2 bits. Digital correction logic generates its result using the 2-bit result from the first stage, 1 bit from
each of the 5 succeeding stages, and 1 bit from the final stage in order to arrive at an 8-bit result. The correction
logic ensures no missing codes over the full operating temperature range.
