The gain of the G = 10 and G = 100 inputs can be changed
by adding external resistors to the internal feedback network
as shown in Figures 4 and 5. The internal gain-set resistors
are trimmed for precise ratios, not to exact values. The
internal resistor values are within approximately
±
30% of
the nominal values shown on the front page diagram. This
makes the external resistor values in Figures 4 and 5 subject
to variation—especially for gains differing greatly from the
initial value.
