FIGURE 10. Typical Connections of Guard Rings
The designer should be aware that when it is inappropriate to
lay out a PC board for the sake of just a few circuits, there is
another technique which is even better than a guard ring on
a PC board: Don't insert the amplifier's input pin into the board
at all, but bend it up in the air and use only air as an insulator.
Air is an excellent insulator. In this case you may have to
forego some of the advantages of PC board construction, but
the advantages are sometimes well worth the effort of using
point-to-point up-in-the-air wiring. See Figure 11.

(Input pins are lifted out of PC board and soldered directly to components.
All other pins connected to PC board.)

7.0 OFFSET VOLTAGE ADJUSTMENT
Offset voltage adjustment circuits are illustrated in Figures
to reduce power consumption while providing typically ±2.5
mV of adjustment range, referred to the input, for both con-
figurations with V
S = ±5V.

8.0 UPGRADING APPLICATIONS
The LMC6484 quads and LMC6482 duals have industry stan-
dard pin outs to retrofit existing applications. System perfor-
mance can be greatly increased by the LMC6484's features.
The key benefit of designing in the LMC6484 is increased lin-
ear signal range. Most op-amps have limited input common
mode ranges. Signals that exceed this range generate a non-
linear output response that persists long after the input signal
returns to the common mode range.
Linear signal range is vital in applications such as filters where
signal peaking can exceed input common mode ranges re-
sulting in output phase inversion or severe distortion.
9.0 DATA ACQUISITION SYSTEMS
Low power, single supply data acquisition system solutions
are provided by buffering the ADC12038 with the LMC6484
(Figure 14). Capable of using the full supply range, the
LMC6484 does not require input signals to be scaled down to
meet limited common mode voltage ranges. The LMC6484
CMRR of 82 dB maintains integral linearity of a 12-bit data
acquisition system to ±0.325 LSB. Other rail-to-rail input am-
plifiers with only 50 dB of CMRR will degrade the accuracy of
the data acquisition system to only 8 bits.
