... The solution shown as a principle schematic by Fig 15 represents the DMOS unity-gain output buffer of the TDA7296A. 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 ...

... The sequence that we recommend during the ON/OFF transients is shown by Figure 16. The application of figure 17 shows the possibility using only one command for both st-by and mute functions. On both the pins, the maximum D93AU014 applicable range corresponds to the operating supply voltage. TDA7296A 9/13 ...

... TDA7296A 4) Clipping Detector Output The TDA7296A is equipped with an internal cir- cuit able to detect the output stage saturation pro- viding a proper current sinking into on open col- lector output (pin 5) when a certain distortion level is reached at output. This particular function allows gain compression facility whenever the amplifier is overdriven, thus obtaining high quality sound all listening levels ...
