Applications

Description

This circuit consists of four 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 can now be more easily

implemented in single power supply systems.

For example, the circuit can be directly supplied

from a standard +5 V, which is used in logic

systems, and will easily provide the required

interface electronics without need for 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.
