(1) Low-power background (LPBG) calibration supply current and power dissipation numbers are in the calibration sleep state. The power dissipation in this mode increases to the background (BG) calibration power consumption during the calibration state. The sleep period can be controlled by the user and long sleep periods will average out the calibration state power dissipation contribution.
