... The main design task one is confronted with while developing an integrated circuit as a power operational amplifier, independently of the technology used, is that of realising the output stage. The solution shown as a principle schematic by Fig 18 represents the DMOS unity-gain output buffer of the TDA7296. This large-signal, high-power buffer must be capable of handling extremely high current and voltage levels while maintaining acceptably low harmonic distortion and good behaviour over frequency response ...

... The sequence that we recommend during the ON/OFF transients is shown by Figure 19. The application of figure 20 shows the possibility of using only one command for both st-by and mute func- tions. On both the pins, the maximum applicable range corresponds to the operating supply voltage OFF PLAY MUTE MUTE TDA7296 ST-BY OFF D93AU013 9/15 ...

... ST-BY 6 BRIDGE APPLICATION 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: – ...
