Another application suggestion is the BRIDGE configuration, where two TDA7296 are used, as shown by
the schematic diagram.
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 realizations. The main advantages
offered by this solution are:
The characteristics shown by figures 23 and 24, measured with loads respectively 8 Ohm and 16 Ohm.
With R
±24V the maximum Pout is 60W.

– High power performances with limited supply voltage level.
– Considerably high output power even with high load values (i.e. 16 Ohm).
