PRECISION VOLTAGE DIVIDER
A precision voltage divider is shown in figure 9. With very light load currents under 100nA, the voltage at pin 2 will be
within 0.002% of V+/2 . Output voltage accuracy decreases with increasing load.
BATTERY VOLTAGE SPLITTER
Positive and negative voltages that track each other can be obtained from a battery. Figure 10 shows how a 9V battery
can provide symmetrical positive and negative voltages equal to one-half the battery voltage.
