Description

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.

MiniSO-8

DFN8 2 x 2 mm

(Plastic micropackage)

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

interface electronics without requiring any

additional power supply.

Pin connections (top view)

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 a single power supply.
