12 _____________________________________________________________________________________
REG B: The data byte writes to register B and the wiper
of potentiometer B moves to the appropriate position.
D[7:0] indicates the position of the wiper. D[7:0] = 00h
moves the wiper to the position closest to LB. D[7:0] =
FFh moves the wiper to the position closest to HB. D[7:0]
is 80h following power-on.
REGS A and B: The data byte writes to registers A and
B and the wipers of potentiometers A and B move to
the appropriate position. D[7:0] indicates the position
of the wiper. D[7:0] = 00h moves the wipers to the posi-
tion closest to L_. D[7:0] = FFh moves the wipers to the
position closest to H_. D[7:0] is 80h following power-on.
Applications Information
Variable Gain Amplifier
Figure 8 shows a potentiometer adjusting the gain of a
noninverting amplifier. Figure 9 shows a potentiometer
adjusting the gain of an inverting amplifier.
Adjustable Dual Regulator
Figure 10 shows an adjustable dual linear regulator
using a dual potentiometer as two variable resistors.
Adjustable Voltage Reference
Figure 11 shows an adjustable voltage reference circuit
using a potentiometer as a voltage-divider.
