Product Details

The ADA4856-3 (triple) is a fixed gain of +2, single-supply, rail-to-rail output video amplifier. It provides excellent video performance with 225 MHz, −3 dB bandwidth, 800 V/μs slew rate, and 74 MHz, 0.1 dB flatness into a 150 Ω load. It has a wide input common-mode voltage range that extends 0.2 V below ground and 1 V below the positive rail. In addition, the output voltage swings within 200 mV of either supply, making this video amplifier easy to use on single-supply voltages as low as 3.3 V.

The ADA4856-3 offers a typical low power of 7.8 mA per amplifier, while being capable of delivering up to 52 mA of load current. It also features a power-down function for power sensitive applications that reduces the supply current to 1 mA.

The ADA4856-3 is available in a 16-lead LFCSP and is designed to work over the extended industrial temperature range of −40°C to +105°C.

    EVAL-ADA4856-3 Circuit Diagram

    Product Details

    These evaluation boards are designed to help users evaluate the ADA4856-3. The evaluation board is a BARE BOARD. There are no components or amplifiers soldered to the board. These parts must be obtained separately from the table below or on the product page. Free samples may also be requested. The unpopulated board enables users to quickly customize and prototype a variety of op amp circuits, which minimizes risk and reduces time to market.

    The User Guide contains all the required documentation to build the board, including schematics, assembly drawing, and Bill of Materials
