It is also possible to use external references other than 10 V with
slightly degraded linearity specifications. The recommended
range of reference voltages is 5 V to 10.24 V, which allows 5 V,
8.192 V, and 10.24 V ranges to be used. For example, by using
the
bipolar can be realized. Using the AD586 voltage reference
makes it possible to operate the AD660 with ±12 V supplies
with 10% tolerances.
Figure 12 shows the AD660 using the AD586 precision 5 V
reference in the bipolar configuration. The highest grade
AD586MN is specified with a drift of 2 ppm/°C, which is a
7.5× improvement over the AD660 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
Configuration section. Use −5.000000 V and +4.999847, as the
output values.
The AD660 can also be used with the AD587 10 V reference,
using the same configuration shown in Figure 12 to produce a
±10 V output. The highest grade AD587UQ is specified at
5 ppm/°C, which is a 3× improvement over the AD660 internal
reference.
Figure 13 shows the AD660 using the AD688 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 precise
biasing for the offset trim resistor, R4.
