[1]With a load connected at the outputs the quiescent current will increase, the maximum of this increase being equal to the differential output voltage offset (ΔVOUT) divided by the load resistance (RL).
[2]The DC output voltage with respect to ground is approximately 0.5VCC.
[3]ΔVOUT = VOUT+ − VOUT− .
