MM: Machine Model
1. Short-circuits from the output to VCC can cause excessive heating if VCC > 15V. The maximum output current is
approximately 40mA independent of the magnitude of VCC
.
2. This input current only 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 this
diode 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 VCC voltage level (or to ground for a large overdrive) for the time duration than an input is driven
negative. This is not destructive and normal output will set up again for input voltage higher than -0.3V.
3. Short-circuits can cause excessive heating. Destructive dissipation can result from simultaneous short-circuit on all
amplifiers. All values are typical.
4. Human body model, 100pF discharged through a 1.5kΩ resistor into pin of device.
5. Machine model ESD, a 200pF cap is charged to the specified voltage, then discharged directly into the IC with no external
series resistor (internal resistor < 5Ω), into pin to pin of device.

1. Vo = 1.4V, Rs = 0W, 5V < VCC+ < 30V, 0 < Vic < VCC+ - 1.5V
2. 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.
3. The input common-mode voltage of either input signal voltage should not be allowed to go negative by more than 0.3V.
The upper end of the common-mode voltage range is VCC+ - 1.5V, but either or both inputs can go to +32V without
damage.

Macromodel
Macromodel
Note:
Please consider following remarks before using this macromodel:
All models are a trade-off between accuracy and complexity (i.e. simulation time).
Macromodels are not a substitute to breadboarding; rather, they confirm the validity of a
design approach and help to select surrounding component values.
A macromodel emulates the NOMINAL performance of a TYPICAL device within
SPECIFIED OPERATING CONDITIONS (i.e. temperature, supply voltage, etc.). Thus the
macromodel is often not as exhaustive as the datasheet, its goal is to illustrate the main
parameters of the product.
Data issued from macromodels used outside of its specified conditions (Vcc, Temperature,
etc) or even worse: outside of the device operating conditions (Vcc, Vicm, etc) are not
reliable in any way.
