This document introduces the Circuits from the Lab® reference designs from Analog Devices, which have been tested and verified to accelerate design and address challenges in analog, mixed-signal, and RF designs. The CN-0405 circuit evaluation board provides a solution for button-controlled adjustment applications using a digital potentiometer.
The CN-0405 is a Circuits from the Lab® reference design that provides a complete solution for replacing traditional mechanical potentiometers with button-controlled digital potentiometers. It utilizes a low-voltage digital potentiometer (AD5116) to control a maximum 20V high-voltage source via simple push-buttons, offering excellent power efficiency and 64 wiper positions.
