TYPICAL APPLICATION CONFIGURATIONS
Figures 7 and 8 show two typical application configura-
tions for the DS1267. By connecting the wiper terminal of
the part to a high mpedance oad, the effects of the wiper
resistance is minimized, since the wiper resistance can
vary from 400 to 1000 ohms depending on wiper voltage.
Figure 7 presents the device connected in an inverting
varible gain amplifier. The gain of the circuit on Figure 7 is
given by the following equation:
Av = –n/(255–n); where n = 0 to 255
Figure 8 shows the deivce operaing in a fixed gain atten-
uator where the potentiometer is used to attenuate an
incoming signal. Note the resistance R1 is chosen to be
much greater than the wiper resistance to minimize its
effect on circuit gain.
