Description
These circuits consist of four independent, high
gain operational amplifiers with frequency
compensation implemented internally. 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.

Notes:
(1)Neither of the input voltages must exceed the magnitude of (VCC+) or (VCC-).
(2)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.
(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 an input diode clamp. In addition to this diode action,
there is also an 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 during which an input is driven negative. This is not
destructive and normal output starts up again for input voltages higher than -0.3 V.
(4)Short-circuits can cause excessive heating. Destructive dissipation can result from simultaneous short-circuits on all amplifiers.
These are typical values given for a single layer board (except for TSSOP which is a two-layer board).
(5)Human body model: 100 pF discharged through a 1.5 kΩ resistor between two pins of the device, done for all couples of pin
combinations with other pins floating.
(6)Machine model: a 200 pF cap is charged to the specified voltage, then discharged directly between two pins of the device with
no external series resistor (internal resistor < 5 Ω), done for all couples of pin combinations with other pins floating.

Notes:
(1)Vo = 1.4 V, Rs = 0 Ω, 5 V < VCC+ < 30 V, 0 < Vic < VCC+ - 1.5 V
(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 load change 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 there is no coupling originating from stray capacitance between these
external parts. Typically, this can be detected at higher frequencies because this type of capacitance increases.
