Description
This circuit consists of two independent, high gain, internally frequency compensated operational amplifiers which were designed specifically for automotive and industrial control system. It operates from a single power supply over a wide range of voltages. The low power supply drain is independent of the magnitude of the power supply voltage. Application areas include transducer amplifiers, DC gain blocks and all the conventional op-amp circuits which now can be more easily implemented in single power supply systems. For example, these circuits can be directly supplied from the standard +5 V which is used in logic systems and will easily provide the required interface electronics without requiring any additional power supply. In the linear mode the input common-mode voltage range includes ground and the output voltage can also swing to ground, even though operated from a single power supply.

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. Short-circuits from the output to VCC can cause excessive heating if Vcc+ > 15 V. The maximum output current is approximately 40 mA, independent of the magnitude of VCC. Destructive dissipation can result from simultaneous short-circuits on all amplifiers. 4. 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 -0.3 V. 5. Short-circuits can cause excessive heating and destructive dissipation. Values are typical. 6. Human body model: A 100 pF capacitor is charged to the specified voltage, then discharged through a 1.5 k resistor between two pins of the device. This is done for all couples of connected pin combinations while the other pins are floating. 7. 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 ). This is done for all couples of connected pin combinations while the other pins are floating. 8. 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.

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 there is no change in the loading charge 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 0.3 V. The upper end of the common-mode voltage range is VCC+ -1.5 V, but either or both inputs can go to +32 V without damage. 4. Due to the proximity of external components ensure that stray capacitance does not cause coupling between these external parts. This typically can be detected at higher frequencies because this type of capacitance increases.

Macromodel
Important note concerning this macromodel
Please consider the 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 (temperature, supply voltage, for example). 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 (VCC, temperature, for example) or even worse, outside of the device operating conditions (VCC, Vicm, for example), is not reliable in any way.
