Part Number:ADS7854
I'm designing a battery operated medical device and I would like to run the ADS7854 with AVDD = DVDD = 3.3V and an external reference of 2.5V on pins REFIO_A / B. The datasheet specs AVDD at 4.5V min. Initial testing all looks good. Are there any technical reasons that would prevent AVDD = 3.3V?
