The gain is internally fixed at 40 dB.  \nFor space reason there is a trend to decrease the number of battery cells. This means a decrease in supply voltage, resulting in a reduction of output power at conventional output stages. The latter is not preferred. Using the BTL principle increases the output power. The TDA7057Q can deliver an output power of 3 W in a speaker load of 16 Ω with 11 V supply.  \nThe circuit is designed such that no external components are required. Special attention is given to switch-on and off clicks, low HF radiation and a good overall stability. The load can be short-circuited at all input conditions.  \nLIMITING VALUES  \nIn accordance with the Absolute Maximum System (IEC 134) .  \n\n| SYMBOL | PARAMETER | CONDITIONS | MIN. | MAX. | UNIT |\n| --- | --- | --- | --- | --- | --- |\n| VP | positive supply voltage range |  | − | 18 | V |\n| IORM | repetitive peak output current |  | − | 1 | A |\n| IOSM | non repetitive peak output current |  | − | 1.5 | A |\n| Ptot | total power dissipation | Tcase \u003C 60 °C | − | 9 | W |\n| Tstg | storage temperature range |  | −55 | +150 | °C |\n| Tvj | virtual junction temperature |  | − | +150 | °C |\n| Tsc | short-circuit time | see note 1 | − | 1 | hr |\n\nNote to the limiting values  \n1.
