OSCILLATOR FREQUENCY (Hz)
FIGURE 11. OUTPUT SOURCE RESISTANCE AS A FUNCTION OF OSCILLATOR FREQUENCY
NOTE:
14. These curves include, in the supply current, that current fed directly into the load R L from the V+ (see Figure 12). Thus, approximately half the
supply current goes directly to the positive side of the load, and the other half, through the ICL7660S and ICL7660A, goes to the negative side
of the load. Ideally, V OUT ～ 2V IN , I S ～ 2I L , so V IN x I S ～ V OUT x I L .
