BRIDGE APPLICATION
Another application suggestion is the BRIDGE
configuration, where two TDA7295 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
subwoofers realisations.
The main advantages offered by this solution are:
