Negative Voltage Converter

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 VIN≤3V, or may be “floated“ for VIN>3V

(3V to 12V)

Ultra Precision Voltage Divider

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.
