Applications Information
Variable-Gain Amplier
Figure 4 shows a potentiometer adjusting the gain of a
noninverting amplifier. Figure 5 shows a potentiometer
adjusting the gain of an inverting amplifier.
Adjustable Dual Linear Regulator
Figure 6 shows an adjustable dual linear regulator using a
dual potentiometer as two variable resistors.
Adjustable Voltage Reference
Figure 7 shows an adjustable voltage reference circuit
using a potentiometer as a voltage-divider.
