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 input
diode 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 during which an input is driven negative.
This is not destructive and normal output will set up again for input voltage higher than -0.3 V.
4. Short-circuits can cause excessive heating. Destructive dissipation can result from simultaneous shortcircuits 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.

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.
