ADA4858-3

Single-Supply, High Speed, Triple Op Amp with Charge Pump
Manufactured by:

Product Details

The ADA4858-3 (triple) is a single-supply, high speed current feedback amplifier with an integrated charge pump that eliminates the need for negative supplies to output negative voltages or output a 0 V level for video applications. The 600 MHz, −3 dB bandwidth and 600 V/μs slew rate make this amplifier well suited for many high speed applications. In addition, its 0.1 dB flatness out to 85 MHz at G = 2, along with its differential gain and phase errors of 0.01% and 0.02° into a 150 Ω load, make it well suited for professional and consumer video applications.

This triple operational amplifier is designed to operate on supply voltages of 3.3 V to 5 V, using only 42 mA of 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 2.5 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 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 a 5 V supply.

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

    Product Details

    These evaluation boards are designed to help users evaluate the ADA4853-3. 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
