Analog Devices ADA4856-3 Video Amplifier Datasheet
The ADA4856-3 is a fixed‑gain (+2) video amplifier designed for single‑supply operation from 3 V to 5.5 V. It delivers rail‑to‑rail output swing (0.1 V to 4.9 V) and supports high‑speed video applications with a 225 MHz –3 dB bandwidth and 800 V/µs slew rate. The device operates over an extended industrial temperature range (‑40 °C to +105 °C) and is available in a 16‑lead LFCSP package.
Key features include low quiescent current (≈78 mA per amplifier at 5 V), a power‑down mode reducing supply current to ~1 mA, and robust ESD protection. Detailed specifications, pin descriptions, and typical performance graphs are provided for both 5 V and 3.3 V operation.
