Description
These circuits consist of four independent, high
gain,
internally
frequency
compensated
operational amplifiers. 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.
All the pins are protected against electrostatic
discharges up to 2000V (as a consequence, the
input voltages must not exceed the magnitude of
V
CC+
or V
CC-
.)

1. Either or both input voltages must not exceed the magnitude of V
CC +
or V
CC-
.
2. Short-circuits from the output to VCC can cause excessive heating if V
CC
> 15V. The maximum output current
is approximately 40mA independent of the magnitude of V
CC
. Destructive dissipation can result from
simultaneous short-circuit 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 diodes
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
CC
voltage level (or to ground for a large overdrive)
for the time duration than an input is driven negative.
This is not destructive and normal output will set up again for input voltage higher than -0.3V.
4. Human body model, 100pF discharged through a 1.5kΩ resistor into pin of device.
5. Machine model ESD, a 200pF cap is charged to the specified voltage, then discharged directly into the IC with
no external series resistor (internal resistor < 5Ω), into pin to pin of device.

1. The direction of the input current is out of the IC. This current is essentially constant, independent of the state of
the output so no loading change exists 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 0.3V. The upper end of the common-mode voltage range is V
CC+
- 1.5V, but either or both inputs can go to
+32V without damage.
4. Due to the proximity of external components insure that coupling is not originating via stray capacitance
between these external parts. This typically can be detected as this type of capacitance increases at higher
frequences.
