Detailed Description
The MAX1184 uses a 9-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.
Counting the delay through the output latch, the clock-
cycle latency is five clock cycles.
1.5-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 subtracted from
the original held input signals. The resulting error sig-
nals 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.
