Features
Description
These circuits consist of two independent, high-
gain, internally frequency-compensated op-amps,
which are specifically designed to operate 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
with the standard +5 V, which is used in logic
systems and will easily provide the required
interface electronics with no additional power
supply.
In linear mode the input common-mode voltage
range includes ground and the output
