Operating — In this mode the amplifier is operating normally. The operating mode is
activated at V
MODE
< 0.5 V.

Applies to all functional modes.
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 (R
L
).
