I am attempting to use the ADS1292 in a low power device, and would like to know the best approach to reducing quiescent power while not in use.
DVDD is coming straight from the battery (2xAA). AVDD is coming from a boosting regulator . When I'm not sampling, should I :
1) Disconnect AVDD but keep DVDD powered?
2) Allow AVDD to sag back down to DVDD?
3) Disconnect both?
