10.2.3 Application Curve

The ±10 V output span with a reference voltage of 2.5 V can be achieved by using values of 30 kΩ, 10 kΩ, and 7.5 kΩ for R3, R2, and R1 respectively. A curve to illustrate this output span is shown in Figure 79. Note: 1% tolerance resistors were used in evaluating bipolar operation.
