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.
