DC CHARACTERISTICS
V
Notes
1. The circuit is DC adjusted at V
2. The DC output voltage, or the common mode voltage on the loudspeaker terminals with respect to ground, is 6.3 V
3. The voltage at pin 14 is approximately
4. The DC output offset voltage step is the difference in output offset voltage in the mute condition and the on condition.
5. Figure 3 shows the relationship between the global crystal temperature and the open voltage at the
6. The maximum voltage on pin 17 is V
