DESC RIP TI ON

This circuit consistsof four independent,highgain, internallyfrequency compensatedoperational amplifiers whichwere designedspecificallyforautomotive andindustrialcontrolsystems. It operatesfrom a single power supply over a wide range of voltages. Operation from split power supplies is also possibleand the low power supply currentdrain is independentof the magnitude of the power supply voltage.

2. The dir ection 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 i nput l ines.

4. 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 i s V to + 32V wi thout damage.

5. Due t o the proximity of external components insure that coupling is not originating via stray capacitance between these ext ernal parts. This typically can be detected as this t ype of capacitance increases at higher frequen ces.

6. This input current only exists when the voltage at any of t he i nput leads is driven negative. It is due to the collector-base junction of the input PN P transistor becoming forward biased and thereby acting as input diodes clamps. I n addition to this diode action, there is also NPN parasitic act ion on the IC chip. t his t ransistor act ion can cause the out put voltag es of th e Op-amps to go to t he V overdrive) for the time duration than an input i s dr iven negative. This i s not destructive and normal output wi ll set up again f or input voltage higher than -0.3V.
