GENERAL DESCRIPTION
The AD8061, AD8062, and AD8063 are rail-to-rail output
voltage feedback amplifiers offering ease of use and low cost.
They have bandwidth and slew rate typically found in current
feedback amplifiers. All have a wide input common-mode
voltage range and output voltage swing, making them easy to
use on single supplies as low as 2.7 V.
Despite being low cost, the AD8061, AD8062, and AD8063
provide excellent overall performance. For video applications
their differential gain and phase errors are 0.01% and 0.04° into
a 150 Ω load, along with 0.1 dB flatness out to 30 MHz. Addi
tionally, they offer wide bandwidth to 300 MHz along with
650 V/μs slew rate.
The AD8061, AD8062, and AD8063 offer a typical low power
of 6.8 mA/amplifier, while being capable of delivering up to
50 mA of load current. The AD8063 has a power-down disable
feature that reduces the supply current to 400 μA. These features
make the AD8063 ideal for portable and battery-powered
applications where size and power are critical.
