Power dissipation
(1)
1.
Power dissipation must be considered to ensure maximum junction temperature (T
j
) is not exceeded.
Short-circuits from the output to V
can cause excessive heating if V
> 15V. The maximum output
current is approximately 40 mA independent of the magnitude of V
CC
. Destructive dissipation can result
from simultaneous short-circuits on all amplifiers.

Input current

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 V
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 be restored for input voltage higher than -0.3 V.

Human body model: 100 pF discharged through a 1.5 k
Ω
resistor between two pins of the device, done for
all couples of pin combinations with other pins floating.
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.
Charged device model: all pins plus package are charged together to the specified voltage and then
discharged directly to the ground.
