Figure 5 shows the AD660 using the AD586 precision 5 V refer-
ence in the bipolar configuration. The highest grade AD586MN
is specified with a drift of 2 ppm/
°
C which is a 7.5
×
improve-
ment over the AD660’s internal reference. This circuit includes
two optional potentiometers and one optional resistor that can
be used to adjust the gain, offset and bipolar zero errors in a
manner similar to that described in the BIPOLAR CONFIGU-
RATION section. Use –5.000000 V and +4.999847 as the out-
put values.
The AD660 can also be used with the AD587 10 V reference,
using the same configuration shown in Figure 5 to produce a
±
10 V output. The highest grade AD587LR, N is specified at
5 ppm/
°
C, which is a 3
×
improvement over the AD660’s inter-
nal reference.
Figure 6 shows the AD660 using the AD680 precision
±
10 V
reference, in the unipolar configuration. The highest grade
AD688BQ is specified with a temperature coefficient of
1.5 ppm/
°
C. The
±
10 V output is also ideal for providing pre-
cise biasing for the offset trim resistor R4.
