Variable Gain Current to Voltage Converter
Figure 12 shows a variable gain current to voltage con-
verter using a potentiometer as a variable resistor.
LCD Bias Control
Figure 13 shows a positive LCD bias control circuit using
a potentiometer as a voltage-divider.
Figure 14 shows a positive LCD bias control circuit usinga
potentiometer as a variable resistor.
Programmable Filter
Figure 15 shows a programmable filter using a dual
potentiometer.
Offset-Voltage Adjustment Circuit
Figure 16 shows an offset-voltage adjustment circuit
using a dual potentiometer.
