TDA7294 general description:
This circuit described here uses two cis tda 7294 for use in stereo (2 x 80Watts) or bridge mode (1x 180 Watts), to configure this setting just four jumpers. To facilitate mounting the circuit has power supply attached. The power is kind of simple symmetrical with a bridge rectifier 6A, and two large electrolytic capacitors , 10000μF the 22000μF/50v. This Power supply will for the two modules. The processor is recommended 22-0-22 to 28-0-28 / 5A, depending on the quality of the transformer is recommended at least 6 amps of current.
- High power performances with limited supply voltage level.
- Considerably high output power even with high load values (i.e. 16 Ohm).
- Rl= 8 Ohm,
- Vs = ±25V
- Pmax = 150 W
- Vs = ±35V
