Description
These circuits consist of four independent, high gain, internally frequency compensated operational amplifiers. They operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage. All the pins are protected against electrostatic discharges up to 2KV (as a consequence, the input voltages must not exceed the magnitude of V CC + or VCC -.)

The maximum output current is approximately 40mA independent of the magnitude of VCC. Destructive dissipation can result from simultaneous short-circuit on all amplifiers. Infinite Iin Input Current 3 3) 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. 50 mA Toper Operating Free-air Temperature Range -55 to +125 -40 to +105 0 to +70 °C Tstg Storage Temperature Range -65 to +150 °C Rthja Thermal Resistance Junction to Ambient SO14 TSSOP14 DIP14 103 100 °C/W

This current is essentially constant, independent of the state of the ou tput 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 uppe r end of the common-mode voltage range is V CC + - 1.5V, but either or both inputs can go to +32V without damage. 4) Due to the proximity of external components insure that coupling is not originating via stray capacitance between these exter nal parts. This typically can be detected as this type of capacitance increases at higher frequences.

5 Macromodel
Warning: 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.
