This product offers a broad supply voltage
operating range from 2.7 to 16 V and a supply
current of only 200 μA/amp (V
= 3 V).
CC
The source and sink output current capability is
typically 40 mA (at V
= 3 V), fixed by an internal
CC
limitation circuit.

1. All voltage values, except differential voltage are with respect to network ground terminal.
2. Differential voltages are the non-inverting input terminal with respect to the inverting input terminal.
3. The magnitude of input and output voltages must never exceed V
4. Short-circuits can cause excessive heating. Destructive dissipation can result from simultaneous shortcircuit on all amplifiers. These are typical values.
5. Human body model: a 100 pF capacitor is charged to the specified voltage, then discharged through a
1.5 kΩ resistor between two pins of the device. This is done for all couples of connected pin combinations
while the other pins are floating.
6. Machine model: a 200 pF capacitor is charged to the specified voltage, then discharged directly between
two pins of the device with no external series resistor (internal resistor < 5 Ω). This is done for all couples of
connected pin combinations while the other pins are floating.
7. Charged device model: all pins and the package are charged together to the specified voltage and then
discharged directly to the ground through only one pin. This is done for all pins.

4 Macromodels
4.1 Important note concerning this macromodel
●All models are a trade-off between accuracy and complexity (that is, simulation time).
Macromodels are not a substitute for 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 (such as temperature or supply voltage, etc). Thus, the
macromodel is often not as exhaustive as the datasheet, its purpose is to illustrate the
main parameters of the product.
●Data derived from macromodels used outside of the specified conditions (such as V
or temperature) or even worse, outside of the device’s operating conditions (such as
V
CC
or V
) is not reliable in any way.
icm
The values provided in Tab le 6 are derived from this macromodel.
