13.13 Application diagrams
With the supply voltage connected to pin 15 it is possible to use the head amplifier above
the maximum of 18 V to pin 16. The internal supply voltage will be reduced to a maximum
of approximately 17 V.
This will be convenient in applications where the supply voltage is higher than 18 V,
however an output voltage swing that reaches the higher supply voltage is not required.
the input configurations illustrated in
application can also be used for headphone applications. However, due to the limited
output current, series resistors have to be used between the output pins and the load; see
