BRIDGEAPPLICATION
Another application suggestion is the BRIDGE
configuration, where two TDA7296A are used, as
shown by the schematic diagram of figure 19.
In this application, the value of the load must not
be lower than 8 Ohm for dissipation and current
capabilityreasons.
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 21 and 22,
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.

4) ClippingDetector Output
The TDA7296A is equipped with an internal cir-
cuit able to detectthe output stage saturation pro-
viding a proper current sinking into on open col-
lector output (pin 5) when a certain distortionlevel
is reachedat output.
This particular function allows gain compression
facility whenever the amplifier is overdriven, thus
obtaining high quality soundall listeninglevels.
