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 +5V which is used in logic systems and

will easily provide the required interface electronics without requiring any additional power supply.

Inthe 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.
