... The solution shown as a principle shematic by Fig3 represents the DMOS unity - gain output buffer of the TDA7295S. This large-signal, high-power buffer must be ca- pable of handling extremely high current and volt- age levels while maintaining acceptably low har- monic distortion and good behaviour over Figure 3: Principle Schematic of a DMOS unity-gain buffer ...

... The current generators formed by T4, T7, zener diodes Z1, Z2 and resistors R7,R8 define the minimum drop across the power MOS transistors of the TDA7295S. L1, L2, L3 and the snubbers C9, R1 and C10, R2 stabilize the loops formed by the "bootstrap" circuits and the output stage of the TDA7295S ...
