... To conveniently serve both needs, its minimum recommended value is 10µF. 3.2 Input stage The TDA7388A’s inputs are ground-compatible and can stand very high input signals (± 8Vpk) without any performances degradation. If the standard value for the input capacitors (0.1µF) is adopted, the low frequency cut-off will amount ...
