Notes :
1.
Short-circuits from the outputto V
CC
can cause excessive heating if V
CC
> 15V. The maximum output current is approximately
40mA independent of the magnitude of V
CC
.
The direction of the input current is out of the IC. This current is essentially constant,independent of the state of the output
so no loading change exists on the input lines.
Vo = 1.4V, Rs =0
, 5V < V
CC+
< 30V,0 <V
ic
< V
CC+
- 1.5V.
The input common-mode voltage of either input signal voltage should not be allowed togo negative by more than0.3V.
The upper end of the common-mode voltage range is V
CC+
- 1.5V, but either or both inputs can go to+32V withoutdamage.
This input currentonly exists when the voltage at any of the input leads is driven negative. It is due to the collector-base
junction of the input PNP transistor becoming forward biased and thereby acting as input diodes clamps.
In addition to thisdiode action, there is also NPN parasitic action on the IC chip. this transistor action can cause the output
voltages of the Op-amps to go to the V
CC
voltage level (or to groundfor a large overdrive) for the timeduration than an input
is driven negative. This isnot destructive and normal output will setup again for input voltage higher than -0.3V.
