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