[1] A minimum load is required at supply voltages of VCC > 22 V; RL = 3 for SE and RL = 6 for BTL.
[2] The amplifier can deliver output power with non-clipping output signals into nominal loads as long as the
ratings of the IC are not exceeded.
[3] With a load connected at the outputs the quiescent current will increase.
