Description

In linear mode, the input common-mode voltage

range includes ground and the output voltage can

also swing to ground, even though operated from

a single power supply.

This circuit consists of two independent, high-

gain, internally frequency-compensated operational

amplifiers, designed specifically for automotive

and industrial control systems. It operates 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

from standard +5V which is used in logic systems

and will easily provide the required interface

electronics without requiring any additional power

supply.
