BRIDGE APPLICATION
Another application suggestion concerns the
BRIDGE configuration, where the two power am-
plifiers are connected as shown by the schematic
diagram of figure. 18.
This application shows, however, some operative
limits due to dissipation and current capability of
the output stage. For this reason, we reccomend
to use the TDA7265 in bridge with the supply volt-
age equal/lower than
±16V when the load is 8;
with higher loads (i.e.16
), the amplifier can work
correctly in the whole supply voltage range.
The detected characteristics of T.H.D. vs Pout
and Frequency Response are shown in fig.19 and
fig.20.
With R1=8
, Vs=+/-16V the maximum output
power obtainable is 50W at T.D.H.=10%.
The quiescent current remains unchanged with
respect to the stereo configuration (~80mA as
typical at Vs=+/-16V).
The last point to take into consideration concerns
the short-circuit protection. As for the stereo appli-
cation, the TDA7265 is fully protected against any
kind of short-circuit ( between Out/Gnd, Out/+Vs
and Out/-Vs).
