Description
These circuits consist of two independent, high-
gain, internally frequency-compensated which
were designed specifically 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 now can 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 without requiring any
additional power supply.
In the linear mode the input common-mode
voltage range includes ground and the output

operated from only a single power supply voltage.
