This circuit consists of four independent,
high-gain, internally frequency-compensated
operational amplifiers, designed specifically for
automotive and industrial control systems. It
operates from a single power supply over a wide
range of voltages. The low power supply drain is
independent of the magnitude of the power supply
voltage.
Application areas include transducer amplifiers,
DC gain blocks and all the conventional op-amp
circuits, which can now be more easily
implemented in single power supply systems.

Shape of wafer
For example, the circuit can be directly supplied
from a standard +5 V, which is used in logic
systems, and will easily provide the required
interface electronics without need for any
additional power supply.
In linear mode, the input common-mode voltage
range includes ground, and the output voltage
can also swing to ground even though operated
from a single power supply.

3. Short-circuits from the output to VCC can cause excessive heating. The maximum output current is
approximately 20 mA, independent of the magnitude of VCC. Destructive dissipation can result from
simultaneous short-circuits on all amplifiers.

e
4. 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 clamp. In addition to this diode action, there is 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 is restored for input voltages above -0.3 V.

5. Short-circuits can cause excessive heating and destructive dissipation. Values are typical and for a single
layer PCB.
6. Human body model: a 100 pF capacitor is charged to the specified voltage, then discharged through a
1.5kΩ resistor between two pins of the device. This is done for all couples of connected pin combinations
while the other pins are floating.
7. Machine model: a 200 pF capacitor is charged to the specified voltage, then discharged directly between
two pins of the device with no external series resistor (internal resistor < 5 Ω). This is done for all couples of
connected pin combinations while other pins are floating.
8. Charged device model: all pins plus package are charged together to the specified voltage and then
discharged directly to the ground.

3. Due to the proximity of external components, ensure that stray capacitance does not cause coupling
between these external parts. Typically, this can be detected because this type of capacitance increases at
