Analog Devices ADA4859-3 Video Amplifier Datasheet
The ADA4859-3 is a triple video amplifier designed for professional and consumer video applications. It operates from a single supply of 3 V to 5.5 V and includes an integrated charge pump that eliminates the need for negative supplies, allowing output voltages below ground.
Key features include a 195 MHz –3 dB bandwidth at a fixed gain of 2, a 740 V/µs slew rate, low quiescent current of 38 mA (down to 2 mA in power‑down mode), and a wide input common‑mode range of –1.8 V to +3.8 V. The device is available in a 16‑lead LFCSP package and operates over an industrial temperature range of –40 °C to +105 °C.
