FIGURE 6. OTHER VOLTAGE RANGES
The AD566A can also be easily configured for a unipolar 0 volt
to +5 volt range or
±
2.5 volt and
±
10 volt bipolar ranges by
using the additional 5k application resistor provided at the 20
volt span R terminal, Pin 11. For a 5 volt span (0 V to +5 V or
±
2.5 V), the two 5k resistors are used in parallel by shorting Pin
11 to Pin 9 and connecting Pin 10 to the op amp output and the
bipolar offset resistor either to ground for unipolar or to V
REF
for the bipolar range. For the
±
10 volt range (20 volt span) use
the 5k resistors in series by connecting only Pin 11 to the op
amp output and the bipolar offset connected as shown. The
±
10 volt option is shown in Figure 6.
