7 / 36 page ![]() ams Datasheet Page 7 [v1-01] 2016-Dec-08 Document Feedback AS7221 − Electrical Characteristics All limits are guaranteed with VDD = 3.3V, VDDHV = 12V, TAMB = 25ºC. The parameters with min and max values are guaranteed with production tests or SQC (Statistical Quality Control) methods. If VDD and VDDHV are to be the same voltage, they must be sourced by the same 2.97-3.6V supply.
