3.4 Output Capacitors.
The low cut off frequency due to output capacitor depending on the load is given by:
with COUT 470mF and RL = 4 ohm it means FL = 80 Hz.
3.5 Pop Noise
Most amplifiers similar to TEA 2025B need external resistors between DC outputs and ground in order to
optimize the pop on/off performance and crossover distortion.
Figure 13.
The TEA 2025B solution allows to save components because of such resistors (800 ohm)are included into
the chip.
3.6 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 connections.
– No ground loops.
– Bypass of supply voltage with capacitors as nearest as possible to the supply I.C.pin. The low val-
ue(poliester)capacitors must have good temperature and frequency characteristics.
– No sockets.
the heatsink can have a smaller factor of safety compared with that of a conventional circuit. There
is no device damage in the case of excessive junction temperature: all that happens is that PO (and
