[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 (∆VOUT) divided by the load resistance (RL).
[2] The DC output voltage with respect to ground is approximately 0.5VCC.
[3] ∆VOUT = | VOUT+ − VOUT− |.
