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.
All the pins are protected againstelectrostaticdischargesup to2000V (as a consequence,the input

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
