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.
