Description
These circuits consist of four independent, high
gain, internally frequency compensated
operational amplifiers. They operate from a single
power supply over a wide range of voltages.
Operation from split power supplies is also
possible and the low power supply current drain is
independent of the magnitude of the power supply
voltage.

Macromodels are not a substitute to breadboarding; rather, they confirm the validity of a design approach and help to select surrounding component values. A macromodel emulates the nominal performance of a typical device within specified operating conditions (i ...
