Description

These circuits consist of four independent, high
gain, internally frequency compensated
operational amplifiers. Th ey o perate f rom a single
power supply over a wide range of voltages.
Operation from split power supplies is also
possible and the low po wer supply current drain is
independent of the magnitude of th e power supply
voltage.

1. Either or both input voltages must not exceed the magnitude of V

2. Short-circuits from the output to VCC can cause excessive heating if VCC > 15V. The maximum output
current is approximately 40 mA independent of the magnitude of V
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 V
for a large overdrive) for the time during which an input is driven negative.
This is not destructive and normal output is restored for input voltages above -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, a two­layer board).

5. Human body model, 100 pF discharged through a 1.5 kΩ resistor into pin of device.

6. Machine model ESD, a 200 pF cap is charged to the specified voltage, then discharged directly into the IC
with no external series resistor (internal resistor < 5 Ω), into pin-to-pin of device.
