TYPICAL APPLICATION CONFIGURATIONS
Figures 7 and 8 show two typical application configurations for the DS1867. By connecting the wiper
terminal of the part to a high impedance load, 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 variable 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 device operating in a fixed gain attenuator 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.
