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. Sign up for this FREE web seminar. Learn how to identify, measure and resolve audio system issues.
