ADA4858-3ACPZ-R7

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 0V level for video applications. The 600MHz, -3dB bandwidth, and 600V/µs slew rate make this amplifier well-suited for many high-speed applications. In addition, its 0.1dB flatness out to 85MHz at G=2, along with its differential gain and phase errors of 0.01% and 0.02° into a 150 ohm load, make it well suited for professional and consumer video applications. This triple-operational amplifier is designed to operate on supply voltages of 3.3V to 5V, using only 42mA 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 2.5mA when the amplifier is not being used. Application includes professional video, consumer video imaging and active filters.
