10 _____________________________________________________________________________________
REG A: The data byte writes to register A, and the wiper
of potentiometer A moves to the appropriate position at
the rising edge of CS. D[7:0] indicates the position of the
wiper. D[7:0] = 00h moves the wiper to the position clos-
est to LA. D[7:0] = FFh moves the wiper closest to HA.
D[7:0] is 80h following power-on.
REG B: The data byte writes to register B, and the wiper
of potentiometer B moves to the appropriate position at
the rising edge of CS. D[7:0] indicates the position of the
wiper. D[7:0] = 00h moves the wiper to the position clos-
est to LB. D[7:0] = FFh moves the wiper to the position
closest to HB. D[7:0] is 80h following power-on.
REG 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 wiper to the position clos-
est to L_. D[7:0] = FFh moves the wiper to the position
closest to H_. D[7:0] is 80h following power-on.
Applications Information
Variable Gain Amplifier
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 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.
