____________________________Typical Operating Characteristics (continued)
(All curves generated using the inverter configuration shown in the Typical Operating Circuits with LV = GND, FSEL = IN or LV,
C1 = C2 = 10μF (MAX1680), C1 = C2 = 2.2μF (MAX1681), and T A = +25°C, unless otherwise noted. Test results are also valid for
the doubler configuration with LV = OUT and T A = +25°C.)
