11. Static characteristics
[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 (RL).
[2]
The DC output voltage with respect to ground is approximately 0.5VCC.
[3]
V
OUT = VOUT+ VOUT
.
