Description
This circuit consists of two independent, high
gain, internally frequency compensated
operational amplifiers, designed specifically for
automotive and industrial control system. 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
also swing to ground, even though operated from
a single power supply.
