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.
