Description
These circuits consist of two independent, high-
gain, internally frequency-compensated op amps,
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 voltage can
also swing to ground, even though operated from
only a single power supply voltage.

These circuits consist of two independent, high gain, internally frequency-compensated op-amps, 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.
