Does the sensor has a voltage dependence? All measurements in the datasheet are done at 2.8V, but does it get better or worse with higher or lower voltages? (From another thread)

Within the power supply range there is no impact in term of performance.​ If you use a power supply between 2.8 to 3.3V and the IMG_005 driver we recommend to enable the compiler option power 2V8 so the I2C standard will be perfectly compliant.
