ADA4856-3 is a single-supply, high speed, fixed gain of +2, rail-to-rail output video amplifier from Analog Devices.
The ADA4856-3 video amplifier from Analog Devices is a single‑supply, high‑speed device with a fixed gain of +2 and rail‑to‑rail output swing. It is intended for professional and consumer video, imaging, instrumentation, base stations, active filters and buffer applications. The device operates over a wide temperature range (‑40 °C to +105 °C) and is available in a 16‑lead LFCSP package.
Key performance features include a 225 MHz –3 dB bandwidth, 800 V/µs slew rate, 0.1 V to 4.9 V output swing, low quiescent current (≈7.8 mA per amplifier) and a power‑down mode that reduces supply current to about 1 mA. The amplifier accepts supply voltages from 3 V to 5.5 V and offers a wide input common‑mode range extending below ground.
