AS1907/AS1908/AS1909
Datasheet - Electrical Characteristics
6 Electrical Characteristics
VCC = Full Range, TAMB = -40 to +125ºC (unless otherwise specified). Typ values are at VCC = +3.0V, TAMB = +25ºC. All limits are guaranteed.
The parameters with min and max values are guaranteed with production tests or SQC (Statistical Quality Control) methods.
