Single-Supply, Fixed G = 2, High Speed, Video Amplifier with Charge Pump

Manufactured by:

Product Details

The ADA4859-3 (triple) is a single-supply, high speed current feedback amplifier with an integrated charge pump that eliminates the need for negative supplies in order to output negative voltages or output a 0 V level for video applications. The 195 MHz, large signal −3 dB bandwidth at a fixed gain of 2, as well as the 740 V/μs slew rate, make this amplifier ideal for high resolution professional and consumer video applications. The amplifier also has a wide input common-mode voltage range that extends from 1.8 V below ground to 1.2 V below the positive rail at 5 V supply.

This triple video amplifier is designed to operate on supply voltages of 3.3 V to 5 V, using only 38 mA total quiescent current, including the charge pump. To further reduce the power consumption, it is equipped with a power-down feature that lowers the total supply current to as low as 2 mA when the amplifier is not being used. Even in power-down mode, the charge pump can be used to power external components. The maximum output current for external use is 50 mA at −3 V.

The ADA4858-3 is available in a 16-lead LFCSP, and it is designed to work over the industrial temperature range of −40°C to +105°C.

    Product Details

    These evaluation boards are designed to help users evaluate the ADA4859-3. 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
