10. Thermal characteristics

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.

∆V

OUT = | VOUT+ − VOUT
