Description
This circuit consists of two independent, high
gain operational amplifiers (op amps) that have
frequency compensation implemented internally.
They are designed specifically for automotive and
industrial control systems. The circuit 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. For
example, these circuits can be directly supplied
from the standard 5 V which is used in logic
systems and easily provides the required
electronic interfaces without requiring 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.
