Designing an application with the analog-to-digital converter (ADC) requires several considerations to optimize for power and performance. This application report discusses the basics of how you would analyze a data sheet and user's guide to design your application. It goes into the fundamentals of how to optimize your design based on the external requirements and available ADC configurations. The goal is to consider various ADC parameters before writing a single line of code. This helps to avoid any unnecessary design changes down the path.
