Notas de aplicación
- Correcting the Low-Frequency Response of the ADS42LBxx, ADS42JBxx for Time-DomaiPDF, 338 Kb, Archivo publicado: mayo 2, 2016
In this application report, simple schemes are described to correct the low-frequency response of ADS42LBxx, ADS42JBxx family of analog-to-digital converters (ADCs). The described schemes are useful for time-domain applications where the ADC samples a low-frequency pulse signal. These schemes are simple to implement in either analog or digital domains with minimal changes to the bill of materials - Why Use Oversampling when Undersampling Can Do the Job? (Rev.
