Abstract: This article discusses how to improve linearity (due to loading of the wiper) and mid-range frequency response of a digitalpotentiometer in VCO control applications by adding a single external resistor between H and W.Digital potentiometer ICs (digital pots, or digipots) are convenient for controlling voltage-controlled devices such as VCOs and as aneconomical alternative for a DAC. In a typical application (Figure 1), a MAX5160 digipot controls the frequency of a VCO, via a 3-wire interface.
