GENERAL DESCRIPTION

The ADA4860-1 is a low cost, high speed, current feedback op

amp that provides excellent overall performance. The 800 MHz,

−3 dB bandwidth, and 790 V/μs slew rate make this amplifier

well suited for many high speed applications. With its combination

of low price, excellent differential gain (0.02%), differential

phase (0.02°), and 0.1 dB flatness out to 125 MHz, this amplifier

is ideal for both consumer and professional video applications.

The ADA4860-1 is designed to operate on supply voltages as

low as +5 V and up to ±5 V using only 6 mA of supply current.

To further reduce power consumption, the amplifier is

equipped with a power-down feature that lowers the supply

current to 0.25 mA.

The ADA4860-1 is available in a 6-lead SOT-23 package and

is designed to work over the extended temperature range of

−40°C to +105°C.
