five clock cycle latency between any particular sample
and its corresponding output data. The output coding
can be chosen to be either straight offset binary or two’s
complement (Table 1) controlled by a single pin (T/B).
Pull T/B low to select offset binary and high to activate
two’s complement output coding. The capacitive load
on the digital outputs D0A–D9A and D0B–D9B should

be kept as low as possible (< 15pF), to avoid large digi-
tal currents that could feed back into the analog portion
of the MAX1181, thereby degrading its dynamic perfor-
mance. Using buffers on the digital outputs of the ADCs
can further isolate the digital outputs from heavy capaci-
tive loads. To further improve the dynamic performance
