These circuits consist of four independent, high
gain,internally frequencycompensatedoperational
amplifiers.Theyoperatefromasinglepowersupply
over awide rangeof voltages.Operationfromsplit
powersupplies is also possible and the low power
supply current drain is independentof the magni­tude of the power supplyvoltage.

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
