The maximum power supply voltage for the TDA7294V is 40V, but it's recommended to operate it between 12V to 36V for optimal performance.
To prevent overheating, ensure good heat sinking, use a heat sink with a thermal resistance of 2°C/W or less, and keep the ambient temperature below 40°C. You can also use thermal shutdown protection circuits.
The minimum load impedance for the TDA7294V is 2 ohms, and the maximum is 8 ohms. Operating outside this range may affect the amplifier's performance and stability.
Yes, the TDA7294V can be used as a bridge amplifier. However, you'll need to use two devices, one for each channel, and ensure proper phasing and synchronization to avoid destructive interference.
To reduce noise and hum, use a well-regulated power supply, add decoupling capacitors, and ensure good grounding and shielding. You can also use noise filters and hum eliminators in the signal path.
