1. The Standby mode (V
quiescent current is < 10 A.
2. To avoid 'pop-noise' during switch-on or switch-off the IC can be muted (V
This can be achieved by a 'soft-mute' circuit or by direct control from a microcontroller.
The value of capacitor Cr influences the behavior of the Supply Voltage Ripple Rejection
(SVRR) at low frequencies; increasing the value of Cr increases the performance of the
SVRR; see

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; see
Figure
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; see
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; see
The TDA8559T 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
of capacitor Cr influences the behavior of the SVRR at low frequencies; increasing the
value of Cr increases the performance of the SVRR; see
The TDA8559T delivers a virtual rail-to-rail output voltage. Because the input mode has to
be high, the input configurations illustrated in
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; see
The value of capacitor Cr influences the behavior of the SVRR at low frequencies;
increasing the value of Cr increases the performance of the SVRR.
