Digitally-Controlled Phase Shift Using the DS1669
Feb 28, 2002
Abstract: This application brief describes how to control analog phase shift digitally using a combination of digital potentiometers and standard operational amplifiers (op amps). It is intended to serve as a design example for engineers needing to implement digital phase shift in a circuitry with no specific application. It presents common op amp phase shift configurations and how to implement them using a digital potentiometer in place of mechanical potentiometers or fixed resistors. Formulas for calculating phase shift are included in the application note.
