BRIDGE APPLICATION
Another application suggestion concerns the Bridge configuration , where the two power amplifiers are
connected as shown by the schematic diagrams of figure 5 “Split Power Supply” , and figure 6 “Single
Power Supply”.
This application shows,however, some operative limits due to dissipation and current capability of the out-
put stage.
For this reason we recommend to use the TDA7269A in BTL with the following supply voltages depending
on the used load impedance (for the single supply consider double Vs) :
The detected characteristics of THD vs Pout are shown in figg: 7, 8 and 9 for the different load impedances.
With Rload = 8ohm , Vs = ±14V the maximum output power obtainable is 30W at THD = 10% (fig. 9). With
Rload = 6ohm , Vs = ±12V the maximum output power obtainable is 28W at THD = 10% (fig. 8). With Rload
= 4ohm , Vs = ±10V the maximum output power obtainable is 20W at THD=10% (fig. 7).
We suggest not to exceed the suggested supply voltages in order to avoid the current limiter intervention.
