ADA4938-1
Preliminary Technical Data
assure that the output has sufficient drive capability. The input
impedance of the V
OCM
pin is approximately 10 kΩ. If multiple
ADA4938-1 devices share one reference output, it is
recommended that a buffer be used.
Table 7 and Table 8 list several common gain settings,
associated resistor values, input impedance, output noise
density, and approximate large signal bandwidth for both balanced
and unbalanced input configurations. Also shown are the input
common-mode voltage swings under the given conditions for
different V
OCM
settings with both dual and single 5 V supplies.
