Voltage and Current Control

(dual op-amp and shunt regulator) (quad op-amp and shunt regulator)

Monolithic IC MM1377, 1378

Outline

The MM1377 incorporates an op-amp with a dual low-input offset voltage and a shunt regulator; the MM1378

combines a quad low-input offset voltage op-amp and shunt regulator. They are appropriate for use in battery

chargers, switching power supplies and other voltage and current control applications. Op-amps with low input

offset voltage are particularly well-suited for handling current detection signals and other low-amplitude signals.
