... Most amplifiers similar to TEA 2025B need exter- nal resistors between DC outputs and ground in order to optimize the pop on/off performance and crossover distortion. Figure 9 The TEA 2025B solution allows to save compo- nents because of such resistors (800 ohm)are in- cluded into the chip JWC1 ...

... TEA2025B - TEA2025D Stability A good layout is recommended in order to avoid oscillations. Generally the designer must pay attention on the following points: - Short wires of components and short connec- tions ground loops. - Bypass of supply voltage with capacitors as nearest as possible to the supply I.C.pin.The low value(poliester)capacitors must good temperature and frequency charac- teristics ...
