Design And Build A Simple DPM
by Dennis Feucht

Digital panel meters (DPMs) are usually used as dedicated digital voltmeters (DVMs) and are also the core of digital multimeters (DMMs). This project entails design derivations and implementation of a simple DPM. Although DPMs are low-cost and available as a single IC, this project presents a case study of a design for new analog engineers of a mixed-signal device. The core of the project is a modified dual-slope analog-to-digital converter (ADC).
