Notes:
1. All specifications are for a single channel based on measurements with both channels in the same operating state.
2. See “4.7.4. Ringing Power Considerations” for current and power consumption under other operating conditions.
3. Power consumption does not include additional power required for dc loop feed. Total system power consumption must
include an additional VBAT x ILIM term.
