ADA4858-3 Single-Supply, High Speed, Triple Op Amp with Charge Pump

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.
