Application Notes
- Using Ceramic Resonators with the ADS1255/6PDF, 233 Kb, File published: Jul 9, 2004
The ADS1255 and ADS1256 each have an onboard clock generator designed to use an external crystal to create the system clock. External ceramic resonators can also be used, since resonators operate with a similar clock generator circuit. Compared with quartz crystals, resonators typically are less accurate and have lower Q, and must be carefully evaluated before being used with either the ADS1255/6 - How delta-sigma ADCs work, Part 2PDF, 136 Kb, File published: Nov 9, 2011
