Output Capacitors
The low cut off frequency due to output capacitor depending on the load is given by:
with COUT 470uF and RL = 4 ohm it means FL = 80Hz.
Pop Noise (Figure 3)
Most amplifiers similar to UTC TEA2025 need external resistors between DC outputs and ground in order to
optimize the pop on/off performance and crossover distortion.

Figure 3
The UTC TEA2025 solution allows to save components because of such resistors (800 ohm) are included into the
chip.
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 value (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 therefore Ptot) and Id are
reduced.
