Description
also swing to ground, even though operated from
a single power supply.
This circuit consists of two independent, highgain, 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 now can be more easily
implemented in single power supply systems. For
example, these circuits can be directly supplied
from standard +5 V which is used in logic systems
and will easily provide the required interface
electronics without requiring any additional power
supply.
In linear mode, the input common-mode voltage
range includes ground and the output voltage can

1. Short-circuits from the output to V
current is approximately 40 mA, independent of the magnitude of V
from simultaneous short-circuits on all amplifiers.
2. Short-circuits can cause excessive heating and destructive dissipation. Values are typical.
3. This input current only exists when the voltage values applied on the inputs is beyond the supply voltage
line limits. This is not destructive if the current does not exceed 5 mA as indicated, and normal output is
restored for input voltages above -0.3V.
4. Human body model: A 100pF capacitor is charged to the specified voltage, then discharged through a
Ω resistor between two pins of the device. This is done for all couples of connected pin combinations
1.5k
while the other pins are floating.
5. Machine model: A 200pF capacitor is charged to the specified voltage, then discharged directly between
two pins of the device with no external series resistor (internal resistor < 5
connected pin combinations while the other pins are floating.
6. Charged device model: all pins and the package are charged together to the specified voltage and then
discharged directly to the ground through only one pin. This is done for all pins.
