... The solution shown as a principle schematic by Fig 15 represents the DMOS unity-gain output buffer of the TDA7295. This large-signal, high-power buffer must be ca- pable of handling extremely high current and volt- age levels while maintaining acceptably low har- Figure 15: Principle Schematic of a DMOS unity-gain buffer ...

... TDA7295 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 ...
