External Resistor Minimizes Digipot Loading
By: Leo Sahlsten

Abstract: This article discusses how to improve linearity (due to loading of the wiper) and mid-range frequency response of a digital
potentiometer 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-c……
