- The supply voltage range is +/- 10V to =/-40V DC.
- Heat sink is required and its thermal resistance should be around 0.038 degree Celsius/Watt.
- Use an 8 Ohm 150W speaker as the load.
- For 100W output the supply voltage must be +/-38VDC.
- The power supply must be well filtered and free of ripples.
- If ripples are present in the power supply it may cause oscillations.
- VM = 1.5V is the mute ON threshold and VM=3.5V is the mute OFF threshold.
- VSTBY = 1.5V is the standby on threshold and VSTBY = 3.5V is the standby OFF threshold.
- Typical input resistance of TDA7294 is 100KiloOhm.
- Frequency response is 20Hz to 20KHz.
- 145 degree Celsius is the threshold for thermal shutdown. Slew rate of TDA7294 is 10V/microsecond and the open loop voltage gain is 80 dB.
- Quiescent current of TDA7294 is approximately 30mA and its maximum value is 65mA.
