Applications information TDA7292 5 Applications information Warning: SOA protection: If the TDA7292 is operated without a load connected to the output terminals, the SOA protection circuit could be activated when a high amplitude and high frequency signal is applied to the input. The frequency and amplitude of the signal able to trigger the protection is a function also of the supply voltage level used. If the above mentioned condition is possible when the speakers are not connected, it is recommended to connect the input to ground or add a dummy resistive load. For example, a 1-kΩ / 1-W resistor can be used at Vcc = ±26 V. If a lower supply voltage is used, the resistor value must be decreased accordingly. 5.1 Applications with dual supply Figure 18.
