Product specification
Low-voltage stereo headphone amplifier
TDA8559
Application 1: SE with loudspeaker capacitor
(see Fig.8)
The value of capacitor Cr influences the behaviour of the
Supply Voltage Ripple Rejection (SVRR) at low
frequencies; increasing the value of Cr increases the
performance of the SVRR.
Application 2: SE to buffer (without loudspeaker
capacitor)
(see Fig.9)
This is the basic headphone application. The advantage of
this application with respect to application 1, is that it
needs only one external component (Cb) in the event of
stability problems.
Application 3: Improved SE to buffer (without
loudspeaker capacitor)
(see Fig.10)
This application is an improved configuration of
application 2. The distinction between the two is
connecting the loads in opposite phase. This lowers the
average current through the SE buffer.
It should be noted that a headphone cannot be used
because the load requires floating terminals.
Application 4: Bridge tied load mono amplifier
(see Fig.11)
This configuration delivers four times the output power of
the SE application with the same supply and load
conditions. The capacitor Cr is not required.
Application 5: Line driver application 1.9 V < V
P
< 6 V
(see Fig.12)
The TDA8559 delivers a virtual rail-to-rail output voltage
and is also usable in a low voltage environment, as a line
driver. In this application the input needs a DC path to
ground, input configurations illustrated in Figs 3 and 4
should be used. The value of capacitor Cr influences the
behaviour of the SVRR at low frequencies; increasing the
value of Cr increases the performance of the SVRR.
Application 6: Line driver application 6 V < V
P
< 18 V
(see Fig.13)
The TDA8559T delivers a virtual rail-to-rail output voltage.
Because the input mode has to be high, the input
configurations illustrated in Figs 5 and 6 should be used.
This application can also be used for headphone
application, however, due to the limited output current and
the limited output power at the headphone, series resistors
have to be used between the output pins and the load.
The value of capacitor Cr influences the behaviour of the
SVRR at low frequencies; increasing the value of Cr
increases the performance of the SVRR.
Application 7: Line driver application 6V < V
P
< 30 V
(see Fig.14)
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
Figs 5 and 6 should be used. This 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.
