AD7195 operation without AVDD

Hi!


In order to save power between the rare conversions we want to switch off the whole 5V AVDD analog power domain while powering the 3V3 DVDD continuously. We want to set the AD7195 into idle mode before switching off the analog power. SPI communication will not take place while analog power is off. Is this method of operation admissible?


Thanks Werner!
