As a result, different devices can also be used in daisy-chaine

In voltage divider mode, a much lower resistance can be achieved
by paralleling a discrete resistor as shown in Figure 69. The

change steps linearly. However, log taper adjustment is usually
preferred in applications like audio control. Figure 70 shows
another method of resistance scaling. In this circuit, the smaller
R2 is with respect to RAB, the more the pseudo-log taper
characteristic behaves.

RESISTANCE SCALING
The AD5260/AD5262 offer 20 kΩ, 50 kΩ, and 200 kΩ nominal
resistance. For users who need lower resistance and still main-
tain the numbers of step adjustment, they can place multip
devices in parallel. For example, Figure 68 shows a simple
scheme of paralleling both channels of the AD5262. To adjust
half of the resistance linearly per step, users need t
