Practically every electronic design attempted today involves an analog-to-digital converter (ADC). In simple applications, the ADC inside an accompanying MCU may be adequate, while extreme-high-frequency applications require high-speed ADCs. Other designs require special attention to the type and characteristics of the data converter.
Design challenges such as the analog input filter usually need extra time. Don’t forget features like decimation, which offers benefits in some designs. The suggestions presented in this article may help with these various design considerations.
