DS1806
TYPICAL APPLICATION CONFIGURATIONS
Figure 6 shows the typical application configuration of the DS1806 as a fixed gain attenuator. In this
configuration, the DS1806 adjusts the attenuation level of the incoming signal. Variations in wiper
resistance are minimized by connecting the wiper terminal of the part to a high impedance load.
Depending on voltage across the wiper, its resistance may vary from 400 ohms to 1000 ohms. Note that
the resistance R1 in Figure 6 should be chosen to be much greater than the wiper resistance R
.
