reference voltages are applied, the range for VO is −3V to
+9V, and CMIR ranges from −1V to +7V. The difference
between the minimum and maximum voltages is constant,
i.e. 12V for VO, only the midpoint has been shifted, i.e. from
0V to +3V for VO.

extended operation were needed in the negative direction,
Figure 4 may be used by changing the signs, and applying
the resultant negative voltage to the −V

layout guidelines and construction techniques. Two very im-
portant points to consider before creating a layout which are
found in the above application note are worth reiteration.
First the input and output pins are sensitive to parasitic
capacitances. These parasitic capacitances can cause
frequency-response peaking or sustained oscillation. To
minimize the adverse effect of parasitic capacitances, the
ground plane should be removed from those pins to a dis-
tance of at least 0.25% Second, leads should be kept as
short as possible in the finished layout. In particular, the
feedback resistor should have its shortest lead on the invert-
ing input side of the CLC411. The output is less sensitive to
parasitic capacitance and therefore can drive the longer of
the two feedback resistor connections. The evaluation board
available for the CLC411 (part #730013 for through hold
packages, 730027 for SO8) may be used as a reference for
proper board layout. Application schematics for this evalua-
tion board are in the product accessories section of the
National databook.
