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.
