Description
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.
D
SO-8
(Plastic micropackage)
Wafer form
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.
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 +5V which is used in logic systems
and will easily provide the required interface
electronics without requiring any additional power
supply.

1. Short-circuits from the output to VCC can cause excessive heating if VCC+ > 15V. The maximum output
current is approximately 40mA, independent of the magnitude of VCC. Destructive dissipation can result
from simultaneous short-circuits on all amplifiers.
2. Pd is calculated with Tamb = +25°C, TJunction = +150°C and Rthja = 125°C/W for the SO-8 package.
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 5mA as indicated, and normal output will be
restored for input voltages above -0.3V.
4. Human body model: 100pF discharged through a 1.5kΩ resistor between two pins of the device, done for
all couples of pin combinations with other pins floating.
5. Machine model: a 200pF cap is charged to the specified voltage, then discharged directly between two pins
of the device with no external series resistor (internal resistor < 5Ω), done for all couples of pin
combinations with other pins floating.
6. Charged device model: all pins plus package are charged together to the specified voltage and then
discharged directly to the ground.

2. The direction of the input current is out of the IC. This current is essentially constant, independent of the
state of the output, so there is no change in the loading charge 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 VCC+ –1.5V, but either or both inputs
can go to +32V without damage.
4. Due to the proximity of external components, ensure that stray capacitancedoes not cause coupling
between these external parts. Typically, this can be detected because this type of capacitance increases at
higher frequencies.
