Description

This circuit consists of two independent, high gain operational amplifiers (op amps)

that have frequency compensation implemented internally. They are designed

specifically for automotive and industrial control systems. The circuit 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 can now be more easily implemented in single

power supply systems. For example, these circuits can be directly supplied from

the standard 5 V which is used in logic systems and easily provides the required

electronic interfaces without requiring any 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 a single power

supply.
