MAX4480-MAX4483 Series Single/Dual/Quad Low Power Operational Amplifiers
The MAX4480‑MAX4483 family are low‑cost, single‑supply op‑amps offering rail‑to‑rail output, 50 µA quiescent current and operation from +2.5 V to +5.5 V. Variants include a single‑amp (MAX4480), a shutdown‑enabled single‑amp (MAX4481), a dual‑amp (MAX4482) and a quad‑amp (MAX4483) in compact SC70, SOT23 and TSSOP packages.
The data sheet provides absolute maximum ratings, detailed electrical characteristics, typical operating curves, pin descriptions and package dimensions, along with application notes such as capacitive‑load stability and shutdown operation.
| Quiescent Current per Amplifier | 50 µA |
|---|---|
| Shutdown Current (MAX4481) | 0.5 µA (max) |
| Gain‑Bandwidth Product | 140 kHz |
| Capacitive‑Load Stability | Stable up to 400 pF |
Each amplifier draws 50 µA of quiescent current.
The MAX4481 includes a low‑power shutdown mode that reduces supply current to 0.5 µA (max).
Yes, they are unity‑gain stable with capacitive loads up to 400 pF.
