Fig. 8 shows a typical connection, which will
provide a negative supply from an available
positive supply without the need of any external
diodes. The LV pin should be connect to ground
for V

capacitors. An external
required to ensure the oscillator will start.
An ultra precision voltage divider is shown in Fig.
10. To achieve the 0.002% accuracy as indicated,
the load current should be kept below 100nA.
However, with a slight loss in accuracy, the load
current can be increased.
