Class H Operation
A Class H amplifier uses a Class AB output stage with
power supplies that are modulated by the output signal.
In the case of the ICs, two nominal power-supply differ-
entials of 1.8V (+0.9V to -0.9V) and 3.6V (+1.8V to -1.8V)
are available from the charge pump. Figure 29 shows the
operation of the output-voltage-dependent power supply.
Headphone Ground Sense (HPSNS)
HPSNS senses the ground return for the headphone
load. For optimal performance, connect HPSNS to the
ground pole of the jack through an isolated trace, as
shown in Figure 30. If HPSNS is not used, connect to the
analog ground plane.
