AD8646/AD8647/AD8648 is a 24MHz rail-to-rail amplifier with shutdown option. This product features low noise, wide bandwidth, single-supply operation and short-circuit output current, and is suitable for a variety of applications.
The AD8646, AD8647, and AD8648 are dual‑ or quad‑channel, rail‑to‑rail input and output, single‑supply amplifiers with low offset voltage, low noise, and low input bias current. They offer a 24 MHz bandwidth, 11 V/µs slew rate, and a shutdown mode (AD8647) for power saving.
These amplifiers are suited for battery‑powered instruments, audio line drivers, photodiode amplifiers, high‑impedance sensors, and automotive applications. The datasheet includes detailed pin configurations, absolute maximum ratings, thermal resistance, and typical performance curves.
