Description

These circuits consist of two independent, highgain,

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.

In the 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.
