MAX1183
Detailed Description
The MAX1183 uses a nine-stage, fully differential,
pipelined architecture (Figure 1) that allows for high-
speed conversion while minimizing power consump-
tion. Samples taken at the inputs move progressively
through the pipeline stages every half-clock cycle.
Including the delay through the output latch, the total
clock-cycle latency is five clock cycles.
One-and-a-half bit (2-comparator) flash ADCs convert
the held-input voltages into a digital code. The digital-
to-analog converters (DACs) convert the digitized
results back into analog voltages, which are then sub-
tracted from the original held-input signals. The resulting
error signals are then multiplied by two, and the residues
are passed along to the next pipeline stages where the
process is repeated until the signals have been
processed by all nine stages. Digital error correction
compensates for ADC comparator offsets in each of
these pipeline stages and ensures no missing codes.
