A minimum load is required at supply voltages of V
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.
With a load connected at the outputs the quiescent current will increase.
The DC output voltage, with respect to ground, is approximately 0.5V
Channels 3 and 4 can only be set to Mute or On mode by MODE2 when V
