BRIDGE APPLICATION
Another application suggestion is the BRIDGE
configuration, where two TDA7296 are used, as
shown by the schematicdiagram of figure 25.
In this application, the value of the load must not
be lower than 8 Ohm for dissipation and current
capability reasons.
A suitable field of application includes HI-FI/TV
subwoofersrealizations.
The main advantagesoffered by this solution are:
- High power performanceswith limited supply
voltagelevel.
- Considerablyhigh outputpower even with high
loadvalues (i.e. 16 Ohm).
The characteristics shown by figures 20 and 21,
measured with loads respectively 8 Ohm and 16
Ohm.
With Rl= 8 Ohm, Vs =
±
18V the maximum output
power obtainable is 60W, while with Rl=16 Ohm,
Vs =
±
24V the maximumPout is 60W.
