Forum Post: ADS1220: Power up sequence of AVDD and DVDD

$

Part Number: ADS1220 Hi, We have one sensor which is powered through a LDO regulator, it's a battery powered device and the regulator must be shut down while not measuring in order to save power The regulator also supplies the AVDD to the ADS1220 so it will also be shut off Is there any problem when DVDD=2.7V~5.5V and AVDD = 0V? We don't want any significant leakage during this state as it would be counterproductive for power saving Thanks
