The AD8591/AD8592/AD8594 are single-supply, rail-to-rail input/output operational amplifiers with shutdown.
The AD8591, AD8592, and AD8594 are single‑, dual‑, and quad‑channel rail‑to‑rail input and output operational amplifiers that operate from a single supply of 2.5 V to 6 V. They deliver high output current (±250 mA), feature an extremely low shutdown supply current (as low as 1 µA), and maintain low input bias currents suitable for precision applications.
The document lists detailed electrical characteristics, pin configurations for the various package options, absolute maximum ratings, and typical performance curves. It also includes application notes such as headphone/speaker amplifiers, sample‑and‑hold circuits, and differential line drivers, illustrating how the devices can be used in portable audio, instrumentation, and communication systems.
