Figure 9-38 shows DAC1006s connected for high-voltage outputs, both unipolar and bipolar. The output current of these circuits depends on the current limit of the LM143 op amp (typically 20 mA). Figure 9-39 shows how a discrete power stage can be added to further increase output current capability (to 100 mA at 100 V). NATIONAL SEMICONDUCfOR, APPLICATION NOTE 271, 1994, P. 668.
