BRIDGE APPLICATION
Another application suggestion is the BRIDGE
configuration, where two TDA7294 are used, as
shown by the schematic diagram 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 solutionare:
- High power performanceswith limited supply
voltagelevel.
- Considerablyhigh output power even with high
load values(i.e. 16 Ohm).
The characteristics shown by figures 27 and 28,
measured with loads respectively 8 Ohm and 16
Ohm.
With Rl= 8 Ohm, Vs =
±
25V the maximum output
power obtainable is 150 W, while with Rl=16
Ohm, Vs=
±
35V the maximum Pout is 170 W.
