I'm designing a LDC1000 circuit for very low-noise performance; one step I'm taking is to connect AGND to DGND at one location.
Would the CLDO cap perform better if connected to GND or AGND? I noticed that it's connected to GND on the EVM schematic:
On AGND:
0.1uF/1uF VDD bypass caps
DAP and GND pad
On DGND:
0.1uF/1uF VIO bypass caps
DGND pad
Rest of the system (MCU, clocks, etc)
Any other suggestions of grounding technique for high-accuracy readings are appreciated.
Thanks much,
Bryan
