Description
This circuit consists of two independent, high-
gain, operational amplifiers that have frequency
compensation implemented internally. The circuit
is 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
suppl y voltage.
Application areas include transducer amplifiers,
DC gain blocks, and all the conventional op-amp
circuits which can now be more easily
implemented in singl e-power suppl y system s . For
example, these circuits can be directly supplied
from standard 5 V which is used in logic systems
and which easily provides the required interface
electronic s without re quiring an y addition al power
supply.
In linear mode, the input common-mode voltage
range inclu des grou nd and the output vo ltage c an
also swing to ground even though it is operated
from a single-power supply.

Notes:
(1)This input current only exists when the voltage value applied on the inputs is beyond the supply voltage line
limits. This is not destructive if the current does not exceed 5 mA as indi cated, and normal out put is restored for
input voltages above -0.3 V.
(2)Short-circuits from the output to VCC can cause excessive heating if VCC+ is < 15 V. The maximum output
current is approximately 40 mA, independent of the magnitude of VCC. Destructive dissipation can result from
simultaneous s hort -circuits on all amplifiers
(3)Short-cir c u i t s can cause excessive heating and destructive dissipation. Values are t ypical .
(4)Human body model: a 100 pF capacitor is charged to the specified voltage, then discharged through a 1.5
resistor between two pins of the device. This is done for all couples of c onnected pin combinati ons while the other
pins are floating.
(5)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 < 5Ω). This is done for all couples of connect ed
pin combinations while t he other pins are float i ng.
(6)Charged device model: all pins and the package are charged together to the specified voltage and then
discharged di rect l y to the ground through only one pin. This is done for all pins.

(2)The direction of t he input current is out of t he IC. This c urrent is essentially const ant, independent of t he state of the output, s o
there is no change in the loading charge on the input lines.
(3)Due to the proximity of external components, ensure that stray capacitance does not cause coupling between these external
parts. Typic ally, this can be detected because this type of capacitance inc reas es at higher frequenc i es.
