Notes
1. The circuit is DC adjusted at VP = 8 to 18 V and AC operating at VP = 8.5 to 18 V.
2. The DC output voltage, or the common mode voltage on the loudspeaker terminals with respect to ground, is 6.3 V
at output power up to 8.5 W. At higher output power, the common mode voltage will be higher.
3. The voltage at pin 14 is approximately 1⁄2VP in the event of a short-circuit, load dump or temperature protection. Any
circuit connected to pin 14 should have an input resistance of >2 MΩ and an input capacitance of <5 nF.
4. The DC output offset voltage step is the difference in output offset voltage in the mute condition and the on condition.
The absolute value of this voltage step is given as +∆Vo mute − ∆Vo on < 150 mV.
5. Figure 3 shows the relationship between the global crystal temperature and the open voltage at the
class-B/class-H pin.
6. The maximum voltage on pin 17 is VP − 1 (VP ≤ 18 V).
