Notes:

1. All specifications are for a single channel based on measurements with both channels in the same operating state.

2. See "3.14.4. Ringing Power Considerations" on page 53 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 (VDD + |VBAT|) x ILOOP term.
