13. Typical performances
13.1. Current consumption
SX8722 mean current consumption in active mode is around 200 [µA], without enabled PGA. The value of the gain of de
PGA can have a negligible influence on consumption in active mode.
Additional consumption depends on the active PGA and on the bias current parameter.
Example 1 : Bias current 25%
PGA1: enabled
PGA2: enabled
PGA3: enabled
SX8722 measured current consumption: ~330 µA
Example 2 : Bias current 100%
PGA1: enabled
PGA2: enabled
PGA3: enabled
SX8722 measured current consumption: ~710 µA
